cloud based add to cart service

need a project made for me and this has to be the BEST work you have ever done and this has to be at the TOP of your priority list. Also, all bids must be bellow $800 Below are my project requirements: I am looking for a very experienced Freelancer to make me a [login to view URL] Add to Cart Service. How this works: At 8am EST / 5am Pacific time on a release day, [login to view URL] will tweet out a link to buy a shoe and then you must click on the link which directly takes you to shoe, choose your size, add to cart and hope you get it in your cart. There are other bot programs out there that automatically do this but I need a program that is more advanced. How the Add to Cart Service NEEDS to work: What this system will do is when Nike tweets the link, in the back-end this Bot must open the link and add lots of sizes to cart. I will need to have a page where I can insert [login to view URL] Accounts, The Size it needs to get, the buyers Phone Number, and an early link to the product. What the bot will do is it will login to the [login to view URL] Account and when the link gets tweeted, You (the freelancer) must make a method where the Bot can login to MULTIPLE [login to view URL] Accounts (around 300) and add different sizes to cart and then log out once the shoe is placed into the cart. This has to be able to login to MULTIPLE Accounts and also must be able to choose any size I need it to and that I will NEED to be able to do in a section (like an admin page) that only I can access where I can put in orders. This admin page also MUST tell me if the bot was successful at adding the shoe to the cart and MUST tell me if it was unsuccessful (for each order). Also: In REAL TIME it email the person who placed the order saying if they got it in their cart and to go log in. The most important part of this is SPEED. You have to incorporate cloud hosting. An example of this is [login to view URL] the creator's website is [login to view URL] . He seems to be able to get any shoe every time with his process. Freelancers this needs to be the best project you have ever made. Freelancer must understand that I will need support if there is a problem,etc. If this Job goes good, there will be a lot more jobs between the freelancer and I.
