Cake PP Auction Site fix and addons, Fast Service Needed!

We have a penny auction website running on cake php and everything works but we need some minor fix and addons. Also, We have already integrated our credit card terminal but bids don't get credited. Below are the list of things we need. The project has to be done fast as we need to start our website at the beginning of April. Please bid if you have previous knowledge of the penny auction sites and how they work. Previous work should be sent for consideration. If we like the service, we will use the same company for our other sites. - Credit Card terminal integration - Coupon module was working but right now when you apply a coupon at check out it gives success message but coupon don't get applied. - XML banner for the home page like [login to view URL] - We have the code for showing the left bids on the right corner of the website. This should be easy to implement. - Buy it now Module (This will be same as swoopo buy it now) Please check [login to view URL] website for similiar buy it now option. - FAQ page design like [login to view URL] - Change captha - We have a search box but it's not working. So you should do a search module where customer can search the site. The website runs on Cakephp with template system. I will provide all the documentation for the credit card terminal.
