Editing a premade script that sends and retrieve information

I had a script made for me a while ago here on Freelancer.com but the coder was a very amateur one. I need someone to edit this code so that some functionality is different, there are new features, and there are many comments in the code so that i can refer to them when I am working with them. The script uses: - PHP - Javascript To accomplish most of the functionality. It uses cURL to send a username and password, send a link, get information and present the information to the user. I am not looking to get this done in a day but I need it ASAP! Once I choose someone for the job I will give them much more information pertain to the script, site and other information. Some features I am looking to add to my script include: - live transload progress of other servers - error checking - file link checking before downloading/transloading - better retrieval of information - many, many comments Also, if you can learn the code, complete the functionality and fixes I request, I can guarantee you future projects and jobs from me as I am looking for a coder who will learn the code and grow with it. Note, that I am also a web designer/programmer so I know my way around code. I will not accept any bids over $100 and no milestones.
