    I know you get this request all the time and I am in now way trying to low ball this project. I studied math and many of my peer in university studied computer science and I first hand know this is a huge project. But I also know the average going rates for software development so lets play fair ball pure business/service. I need to develop a website with a monthly registration fee as well as a very small transaction fee. As you may know Vaporizers and associated items are becoming a large consumer interest. I am the founder of Vaporize-IT Distribution Corp. I have created a web or net between local (socal) wholesalers and local (socal) retailers. BUt this is growing to large for me to manage on my own. My niche is that &quot;on hand inventory&quot; is deliverable within 6 hrs and my &quot;on call inventory&quot; is available in 24 hours. We mark up the item on average (emphasis) average 35%. My on hand inventory is once the order is received is delivered by a driver within 6 hrs and my on call is delivered by a drivr within 24hrs. BUT! I want to give a retailer the option of being a wholesaler as well for certain items. If they must order some they might as well order a lot and wholesale a portion to another retailer. THey can choose to send it themselves, or have a driver of mine pick it up and deliver the item for an added cost than can be divided by both parties evenly. THe seller should be able to choose his payment option be it Cash on Delivery or Cash on Order. It is imperative that this site is exclsively for retailers (who identity should be masked with only location of store available to view to prevent retailers fueling neighboring competing stores. This exclusivity can be maintained by invite only memebership. Im willing to put up funds to have this done well for I feel it has a huge growth potential.

    Hello, I need to produce (Photoshop made) app presentation images, that demonstrate the apps functions in actuality.I have already had some images made by another app presentation image designer (Image 1).However, there are 3 produced app function presentation images from the bunch that I&quot;m not happy with (Image 2, Image 3, Image 4).I want these images to look more professional. They need to look like they are showing an &quot;augmented reality&quot; (https://www.youtube.com/watch?v=oH_LfXnklRw) image (if someone has prior knowledge of working with Photoshop to produce &quot;augmented reality&quot; type images before, that will be a bonus). They need to produce arrows and icons (+ a navigation map, at the top left-hand corner) in a similar fashion as shown in my app product concept images, &quot;Image 5&quot;, &quot;Image 6&quot; (in these images, the arrows are the same color, and need to appear as if actually are against the floor [NOTE: the text in the left pointing arrow says &quot;Science section&quot;, the text in the right pointing arrow says &quot;History section&quot; and the text in the forward pointing arrow says &quot;Reading areas&quot;. The text in the arrow of &quot;Image 6&quot; says &quot;Napoleonic Wars&quot;. The map can be made in enough detail as to seem as something you would see in an actual app) and &quot;Image 7&quot; (the arrow needs to look like an &quot;augmented reality&quot; looking floating arrow, the book needs to look slightly highlighted in red, the information box needs to look like it&quot;s popping out of the book in similar way as shown in &quot;Image 7&quot; [you can choose how the information is layout, so long as it looks like you would see in an &quot;augmented reality&quot; image, and it looks professional so nothing too flashy]).Needs to have a presentation similar to &quot;Image 1&quot;, &quot;Image 2&quot;, &quot;Image 3&quot; ect., but better looking.If accept your offer, I&quot;ll send over the .psd file images of &quot;Image 2&quot;, &quot;Image 3&quot;, &quot;Image 4&quot; (as the previous designer left them) and you can get to work on them with Photoshop.
