Prestashop Custom Coding - Programmer and PS Expert Required

Hi,

I'm a web developer/designer currently working with a client on an eCommerce project built using Prestashop. The client has decided that they would like to incorporate a number of new features to the Product pages, none of which can be added in the more traditional manner and unfortunately require some expertise a little way out of my own area of skills. The job will require complete re-working of how the current system works for each product on its individual page, incorporating such things as a custom price per weight checker, a postcode checker (for delivery costs) and a few other minor things.

So with this in mind, I am seeking a talented and reliable programmer who preferably has a solid understanding of the Prestashop platform and its back-end. They need to be a great communicator as I expect to be in touch with them regularly throughout so as I can oversee things (mainly as I have already spent a great deal of time on the project so I'm kind of protective of it). I will provide a URL and more in depth details at a later time. For now, I'm looking to get the ball rolling.

Please put in your best and most honest bid at a fixed rate. No time wasting please and I would also like to see a solid portfolio and all round good customer feedback.

Thank you for your time.
