Prestashop Payment Gateway developer

Please read requirements carefully.

I have a prestashop shop. www.indiechicboutique.co.uk

I am using PaymentSense as my gateway people. I bought a module for the payment system but it does not work. I need someone to develop a module so that payments go through on my web site. I don't want people being redirected elsewhere to make the payment.

I am attaching the intergration pack I got from PaymentSense. Please send over a bid as a flat fee. I have come across people who bid low but actually want a lot more/ hour/project. Don't waste my time please.

Real bids, please. Also it would be great if you could communicate directly with the paymentsense development people with questions. I don't want to be a middle man since I have no clue about developers talk.

Cheers
