It's a matter of having only waited three hours before bumping. GMs are few and far between, or already have their own groups. In the end, you've also provided potential GMs no information about what you're looking for, and chances are, most won't chance taking on an entire group without some idea of what they want, or their style of play. But you might get lucky. I, personally, find that experienced 3.5 groups edge on the side of campaign-ruining, because of the burden of knowledge on the GM is much greater than the PCs, who end up all pulling from different splats. If you're not familiar with how Feat X interacts with Alternative Class Feature Y, chances are your PCs will steamroll through everything, with the only recourse of letting them, or politely asking for rebuilds. A matter of setting expectations on both sides of the fence is probably what will attract a GM moreso than just asking for one; if someone has an idea of what you're looking for, and what they can expect from you, as players, they may already have something appropriate, or be more willing to take that chance and tailor something for you guys.
