My goal is to launch a professional-grade hair dye that can be produced at scale by a contract manufacturer in the United Kingdom. I already have brand positioning and target shade range defined; what I do not have is a fully validated, production-ready formula. Here is the support I need from an experienced cosmetic chemist/formulator: • Create a complete hair-dye formula that meets UK/EU cosmetic regulations, including INCI list, percentages, and processing instructions. • Supply bench-scale prototypes with stability and performance data (wash-fastness, grey coverage, skin-patch irritation). • Advise on ingredient sourcing that keeps the supply chain within the UK or EU where possible. I am particularly interested in options such as ammonia-free systems, long-lasti...

I want to bring an all-natural veterinary shampoo to market—something gentle enough for routine bathing yet robust enough to leave a noticeable shine and healthy coat. The formula should as musch as organic possible; no synthetics, parabens, sulfates, artificial fragrances, or colours. I am not looking for a medicated flea-and-tick wash, just a safe everyday cleanser that can be marketed as “normal/organic” for dogs with average or mildly sensitive skin. What I need from you: • A complete bench-scale formula (percentages and preferred suppliers) that meets organic certification standards in major markets. • Clear manufacturing instructions, including pH targets, mixing order, preservation strategy, and viscosity control. • Guidance on stability and...

I already have a working ESP32 design in KiCad and need it brought to its final, production-ready form for a commercial product that must clear CE. The job centres on three key changes: swapping the Micro-USB for a USB-C connector, integrating a Li-Po charging IC, and tweaking the board outline and component placement so everything fits a new enclosure while preserving optimal antenna clearance, decoupling, and thermal performance. Please keep manufacturing constraints in mind and pass every KiCad DRC before delivery. Timeline is tight three days from award so I’m looking for someone who can move quickly yet meticulously.

I already have early-stage tech packs, line drawings and illustrations for a small collection that spans dresses, shirts, pants, skirts and a few other silhouettes. What I now need are full, factory-ready tech packs that incorporate several late-stage edits so the first physical prototypes can be cut without a single follow-up email from the sample room. The work involves: • Translating my existing sketches and rough tech packs into professional, production-grade documents. • Applying my own custom guidelines for layout, annotation style, and construction terminology. • Tweaking fit, detailing and fabric call-outs where my margin comments flag issues or where you spot inconsistencies. Typical information that must be included for each style: precise flat drawings (Ad...

I’m building a new women’s clothing line and want a creative partner who can guide the entire design process—from refining the brand concept to handing over factory-ready tech packs. The brief is intentionally open: I’m still deciding whether the first drop should lean toward dresses, elevated everyday pieces, or occasion looks, so I value a designer who can explore a few directions with me and back each idea with mood boards, sketches, fabric suggestions, and clear construction details. Here’s what I need you to handle: concept development based on the brand story I’ll share, professional flat sketches and 3D visuals where useful, fabric and trim sourcing guidance, and complete tech packs with measurements that a manufacturer can follow without further...

I’m ready to move from vague inspiration to a concrete plan for a new product or service, and I’d like a skilled partner to guide that journey. The only firm direction so far is that we’re creating something new; whether it ultimately becomes a web platform, a mobile experience, or even a physical solution is still wide open. I’m deliberately keeping the brief flexible so your research, creative thinking, and technical insight can shape the best path forward. Here’s what I need from you: • A concise discovery phase that captures the core problem, target audience, and competitive landscape (desk research, lean market analysis, or customer interviews—whatever you know works). • A validated concept document outlining key features, user flows,...

I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...

I'm looking for an expert in oral care formulation to help create a specialized mouthwash. My goal is to develop a product tailored with specific benefits, including being gentle on sensitive teeth, delivering quick whitening results, and ensuring long-lasting effects. I'm also aiming for a peroxide-free formula. While I have some ideas for the active ingredients, I will need your guidance and expertise to finalize them. Approval from laboratories in both Pakistan and Dubai is essential. If you've got experience in crafting innovative oral care solutions and navigating regional compliance, I'd love to collaborate with you!
