I require a web design that will cater to large volume file upload and download transactions. The type of files involved are graphics/photos (web site built from scratch). The website will cater to two type of profiles registered - expert artist and consumer customer (anyone). The purpose of the website is to receive photo's from a consumers smartphone via a custom app for android and IOS iphone/tablet. The other option is direct upload to the website by the consumer online via their PC. Once photos are uploaded to the site and processed (enhanced) by the client artist, the photo will be sent back to the consumer customer for a small fee. If accepted, a transaction of payment will need to processed before it's download back to the consumer customer.
There are other rules of how the website is to function and I can provide a word document explaining the business operations of the website. I need advise on payment processing and data encryption of users details.
I will also require a confidentiality agreement for this project.
I look forward to your response and perhaps coming to terms for the project scope, duration etc and a fair and accurate cost. I also require acknowledgement that the source files will be provided to me for future development requirments as a safe guard.
