Sound wav -> mp3

Hi all, I need a really big favour done. I have a .wav file (it’s a loop, that’s 1mb) that I want to make smaller, and into mp3 so it’s small in Flash. I tried all of the wav to mp3 conversion tools, but they ALL leave a gap in front and behind the new .mp3; so the new loop, when looped, has gaps in the middle. Can someone who has a pro Sound edditing program (Such as Acid Pro stuff, that can accurately edit/convert sounds) please convert this file for me?

Since I Paid for this loop (dun dun dun), I don’t want to just post it out in the public here. So someone who has a program that can convert, please PM me =)

Thanks a lot =)
