Oscommerce project for Fuzzoid or any other good providers

I'm looking for a service provider to make the following changes to an oscommerce site, the oscommerce site is already highly modified so you will be working on modified files, although the changes are fairly straight forward. 1. Change currency like [login to view URL] In oscommerce the change currency is in infoxbox which is not very good. Can you make it like lightnbox so the change currency is right next to the product price? Can you make it so that change is made using ajax or something instead of a page refresh. 2. "Add this" pop out dissapears under "videos being watched now" I need to "Add this" to stay on top. 3. I've installed the RMS Returns System contribution: [login to view URL],1136 When you try to return an item, the [login to view URL] page goes blank, I need this page to function correctly. 4. In the returns system if the customer chooses a store credit I would like the discount code to be automatically generated. I have the Discount coupons contribution installed so the code could come from there. 5. Cancel order button next to each order in the customers account page. Im not sure how admin should be notified of this though. I need the date and time the order was canceled and possibly tie it in with the returns system contribution mentioned above. The cancel order button should not be available in certain order statuses, like if the order was already dispatched or refunded. I need some form of notice for the customer stating the request to cancel the order has been sent and you will receive a reply shortly. I have an ajax private message system designed by another service provider from here, I would like this cancel order button to tie in with the ajax private messages, so if the customer cancels the order, the pm is sent to the admin with detials, then admin can reply to that pm and tell the customer the cancel was approved or whatever. 6. I need a "you have a new pm pop up, click to view or dismis" so if I send a pm to a customer who is currently logged in they will get the pop up whereever they are on the site. 7. I need a "number of pm's to be replied to before yours" in the customers account page so the customer can tell how many pms are waiting resonse. The number should refresh by ajax automatically without page refresh every minute. 8. The ajax private message system was developed on large widescreen monitor. If the customer has a small monitor then they cant read the message or sometimes its cut off becuase of the width. I need the messages to display on small monitors. This should be easy enough just adjusting the widths of the messages code so it displays correctly. 9. In the admin side for the private messages I would like only the new messages and messages waiting for a reply to show in the inbox. If you have hundereds of messages it makes it difficult to find messages which need a reply or have not been replied to. 10. I have the ajax private messages installed on differnet sites, I want to view all the private messages on one site to save me having to logon to each site to check. I need to keep the messages from each site in seperate tabs, not have all the messages into one page. The name of each site should be displayed on the tab so I know which messages they are for. 11. I need the private message system to send a predefined pm to the customer at a predefined time after their order was dispatched (5 days after as default). 12. I need the product scroller above the product in [login to view URL] in [login to view URL] above the product. Just product picture and price with link to product. The products to display should only be from the same category as the main product. I think 4 or 5 wide would be enough otherwise it starts to stretch the center table. 13. I have a flash header but sometimes with Firefox the flash movie does not load when your clicking through the site. If you refresh the page the flash movie loads fine. I need the flash movie to be displayed and never dissapear. In IE the flash movie does not load at all and an Java error is displayed at the bottom of the page. I need the flash movie to display correctly in all IE and Firefox versions and fix the Java error. 14. "Videos being watched right now" displayed a red cross in account.php. I need the videos to display as they should. 15. There is a small problem with the shipping totals, the international shipping rate is calculated at 5 times what it should be. If I copy that product to make a new product, the shipping is calculated correctly. I dont want to add lots of new products so I need the shipping price to be calculated at the correct rate. 16. In alibaba com on the product page they have product details, shipping and packaging, payment terms tabs. I would like this feature on my [login to view URL] page. I have some tabs just now which should be removed after this. Do not bid on this project if you have no intention of completing all the work. This project will be awarded to the service provider who can complete the project in the least budget and the quickest time.
