I am working on my girlfriend finding project and it seems to me that every girl have a BF.

I would say it is about 97% of people who are in a relationship. Do I have to approach 1000 girls to find a single HB?

I'm not sure where you are looking if you believe that most girls have a boyfriend, most likely they are just saying they have a BF, its called the BF objection or rejection. Its an easy way for girls to get rid of wussy guys...

I'd recommend going clubbing as I'd say over 70% of the girls at clubs are single or obviously with there bf holding there hand etc...

That is not completely true, girls say they have a boyfriend all the time. It's usually there way of saying:

"I'm not interested, go away"

*EDIT*

If she drop the I have a boyfriend bomb on ya:

HB: I have a boyfriend.
You: Yeah I had a goldfish when I was 9.
HB: What?
You: Oh I thought you wanted to talk about stuff that didn't matter.

HB: I have a boyfriend
You: Yeah I totally wrestled a gnome this morning
HB: What?
You: I thought today was make up stupid stories day, hey you started it with the whole boyfriend thing

See where I'm going here? Delivered properly basically(good tone, body language) anything can be a winner. Don't just give up when a shit-test/bitch-shield/LMR comes up. Work your way around.

If you do find that she really does have a boyfriend I'd stop gaming her but thats just me, I wouldn't want someone trying to seduce my girlfriend.
