Myself, I did alot of google/yahoo image searching and learned how to use "gimp"...atleast the basics. Otherwise there are alot of people on here that do an awesome job and take requests in this thread....

Somewhere there is also a link to a photobucket user that has a ton of logos too.
But for the most part, it's just digging...which sounds like your doing, so I dunno why your having such a hard time. I'd suggest posting a request in that thread.
Sorry, Im probably not much help.
