Looking to build a site very similar to helpingdoc.com with Twilio SMS service and Stripe merchant account billing. There is a front end website where users can view available appointments for different professionals based on Google map API location service, and there is a backend admin panel for the professionals themselves to input available appointment time/duration. Backend admin panel will also have customary settings tab to control calendar, client list, recall/reminder list, Twilio messaging function, business information, billing options for SMS and monthly service. Backend calendar function must have left click as drag-&-drop functionality similar to the OLD & GOOD Yahoo email (not the "new" horrible Yahoo email). This enables professional users on the admin panel to add appointments quickly and to process the booked appointments into different categories like confirmed, cancelled, rescheduled, cannot contact, etc. Backend calendar must be able to synch with Google Calendar. Twilio SMS is used to send text msg to remind users of upcoming scheduled appts and to verify user identity during appointment booking to reduce fake appointments by using SMS verification code. SMS will also be used to as marketing tool, to spread the word. Stripe merchant account is used since it's one of the cheapest and easiest way to implement billing function w/o adding another layer of development onto the website. The will also need to be a MASTER admin panel to control the website and its users.
Looking for someone with good sense of design and ability to code PHP, MySql, and APIs for Twilio, Stripe, and Google map. Coding and database integration must be efficient and elastic to accommodate for future growth of website. Please don't promise more than what can be delivered on a timely and cost-efficient basis. Do not need hosting. Have dedicated server, domain, and host ready to go. Source code must be transferred at end of project.
