just try the different games out, whatever works best for you. Dont think this can work out well without at least some kind of starting roll. You should at least deposit $50-$100 and then start off with the lowest stakes sit n gos and see how it goes. Dont step up before you havent put enoug a decent sample size of games at that limit and feel like ur a consistent long term winner there. Also, at the lower stakes I think your hourly $ev is higher in sngs and mtts as in cashgames so id rather start off with these games. Not sure how much books you read on poker but if none you also should do this. Kill everyone is a good book for sngs and mtts for example.
