six simple bugs fixes

I'm looking for a freelancer who can fix these bugs in our private message script and oscommerce shop: 1. login shuts tab down/makes empty tab in browser 2. write feedback link visible only when order status = delivered, (order_item _status 10). This will be 1 small line addition of code. 3. keep product dispatched checkbox checked when item status is changed 4. Fix heremes and interparcel tracking module. We are using the osc tracking module but 2 of the 3 courier modules we use are not loading the tracking info. 5. Add product description next to product search results 6. Remove this code from private message replies: Content-Type: text/plain; charset=UTF-8. The code is added to the message when we reply from a mobile device. I have a budget of $40 for this project, it should be easy tasks for anyone who is an expert in php and ajax. I will release the funds only when the job is completed.
