ltc/ btc module for prestashop

Developer must be good in php and has a very good knowledge of prestashop. I need a module developed to give me the ability to accept payments in Bitcoins and Litecoins on my prestashop. The price is set in dollars and is converted to LTCs and BTCs according to the BTC-e exchange rate. A check of the rate is done every 10 minutes and the price auto adjusts itself. Both my e-currencies address are on Btc-e which provides an API. p.s. the code should be clearly written. No passwords or e-currencies will be given to the developer. The developer will have to test his code and he/ she will tell me were to insert the appropriate data (psswds etc). Delivery time: maximum 5 working days
