Convert AVI file to WMV

Hi, a client of mine is a singer who wants to post a video file on his website of him performing. All he has is a huge (189MB) AVI file. I am told that the way to post this on his website is to first convert it to a WMV file (I am open to other suggestions). Rather than take the time to post the file here, I have ftp'd it to a server and will provide the login into for accessing it. If you need this prior to submitting your bid, please ask and I will provide it. NOTE: THIS IS ONLY 1 OF 6 FILES THAT NEED TO BE CONVERTED. Please submit your official bid for this 1 file but also let me know the price to convert all 6 files. Thanks for taking the time to read this. -- Steve
