Olhip, the BEST way to get a chick is tell her you're not looking for a gf...that you just want to take your time, and get to know someone as a friend...lol stuff along that lines seems to just work...seriously.
If a guy I was interested in told me he wasn't looking for anything serious AT ALL...I'd say "Peace out, lifes too short to wait for ya buddy." We'd be friends but a guy who doesnt act on his instincts is really unappealing...gotta have some balls!
