dear, i don't think that u wana do it on a commercial basis. it's very simply, instead of all headaches for CR blah blah, make it simple. start in within ur own community or u can use qatarliving forum but to keep urself on the safe side, give an email id or a cell no not on ur name. where there is a will, there is not only 1way, a lot of ways. go for it and have fun. trust me, if u want to follow the legal ways here, u'll grow old and end of the day, the result will be NOTHING.
good luck ;-)
