There are several different anime-ish "avatar-makers" you can use other than the one you've already tried - I've used
http://www.tektek.org/dream/ several times, once you've created an image you can 'save image' to you computer, then upload it to an image-sharing site (I use "Imageshack" myself), then you can use one of the (usually) provided link options to post the image here! (Imageshack provides both 'direct' links where you only see the link, and 'forum' links that actually put the picture itself as the link).
Okay, you likely already know a lot of that, but I figured it couldn't hurt to provide ALL the info, just to be safe/sure

There is also another more local option, take you description, and post it here:
viewtopic.php?f=76&t=11140 , and one off the many PtP-ers who are also artist may draw up a reference image for you! (I would offer to do so myself, but my shedual is a little busy right now).
Hope all of that is of use,
