Anyone know of a free website where you can make your own custom ringtones?

Im looking for a GOOD FREE website (with no BS) where i can load a portion of a real song into it and make my own ringtones. I need to increase the volume of my ringtones very loud because i run loud woodworking tools all day and i cant hear the phone ring. Ive payed for ringtones from Verizon in the past but they are useless because they arent loud enough. Ive tried doing this in Windows Movie Maker and some times it works. I import a song, cut it to length fade in fade out increase volume save it and send it to from email to my phone. However i keep having to send and resend the tones i make there because some times i get them too loud and they are distorted. It takes forever to get it exactly right. Now WMM is acting up on my computer and the tone sounds like crap no matter what volume it is. Anyone know of a site like this? Or if i can do it an easier way? I have Windows XP. Serious answers only please.
