Fix some bugs on Oscommerce Integration

1) Fix Integration with Dalpay (must have experience) right now cart is not totaling up Properly my guess is with Gift Wrap Added I believe it adds to total but doesn't charge total. When IPN comes there is an error. Fix this please. Also if there is gift wrap allow comments to be put on order and let me receive that in order details in my card. If no gift wrap delete that comments section. 2) Replace at top On Sale. With Best Sellers. make three section MEN WOMEN SKIN Care and allow me to put the products there. One Page only five from each category. 3) There is a way I get the feed and what happens is it sometimes says server error, although it appears to finish 7/10 running it it crashes. It populates the database via ftp. But runs for 15 minutes.. sometimes i guess it seems to give error. Then only after it populates the products 5000. and it is finished I run a price updating tool and it deletes all out of stock and wrong products. It would be good to fix the problem of crashing. and run it as a cron job. Only when it finishes populating the catalouge then trigger a price updating tool. (perhaps the pricing tool needs to be changed if it is a cron) on a tight budget need an expert to do it. Only apply if you are familiar with dalpay and also the rest. I already have an order page for dalpay its been closed to take orders it could be re-nabled to test... then when it finishes the test, it will be open for orders. Bid Properly with the amount, and also pm me. I will only release when everything is done and works. And dalpay accepts it. They accepted it before but then the giftwrap made the total orders wrong i advised them and they diasbled the payment page for now.
