eCommerce expert (PHP, mySQL, JS, JQuery, etc)

I'm looking for an eCommerce expert to establish commercial eCommerce server integration (not PayPal, but more than PayPal) in my site. I want to be able to charge users in specific ways that I will discuss with short-listed coders. To be eligible to work with me: 1. You must be very quick to understand complex issues and create solutions that optimise the user experience. 2. Provide your long term rate and lock it in for at least 6 months of working together. 3. Be available to work full time on my project. 4. Be able to show me at least 3 past projects that you have done related to eCommerce. From there we will select a eCommerce provider you are most experienced with. 5. Be an excellent coder. I will know if you are not as I have been doing this for decades and we will share screens so you will work on my machine to install code and I will ask you to demo using your computer. I have software to do this.
