Talk to Littli in your apartment and agree to rob a bank. THEN do not spend it on ANYTHING ELSE but the club. Do not buy the girls the 7k EACH cloths until you get them dancing in your club(do buy them dance cloths). Avoids almost all of the grind for money that way.
If you rob the bank(yea you take exactly 1,000,000 when you could take 10,000,000)...anyway if you buy the 21k in cloths,some alchol,chocolate,ect...you set yourself up for WEEKS of 8 hour shifts at the coffee shop and freelance writing in your office with no way to avoid it. So after you rob the bank spend as little as possible until your club is up and running.
PS. NEVER gift Becca makeup...she does not wear any and will be pissed off you think she is not pretty enough.
