erm, apply for a decent job.
(1) invest the 20k in stocks; insas (currently 0.87), furnweb (0.82), lafmsia( 8.83) ~ you choose which one to invest.
(2) every 3 mths put in the savings you put aside from your salary
(3) 36 months later, the money in these counters would be more than the small stall you intend to set up.
