bicycle biz so far

so i have my heart set on getting a fixie sometime before my brithday but the hardest part is finding one or a good bike for a conversion. my email is filled with conversations between me and the Sheldon Brown; the other half are me coming soo soo close to finding a good bike then finding out its a tad too big for me.

i came close to having this one, its a schwinn world sport, for $120 but it turned out to be an inch or two too tall. i asked alex and he said he'd help me fix one up once i get my hands on one. i figured that i'll just get a flip-flop hub, some chopped handle bars, and leave the front brake on (as you can tell, i have it all modeled in my head to be like the one up there, the one i almost had).
i have two people that im talking to who actually live in SCV and are selling their bikes but what im really shooting for is finding one that fits in my uncle's garage; i just remembered that he as like four or five bikes from like twenty years ago.
