trading income

Hi guys, I've been investing in the market for 5+ years and have been moderately successful, more so in the last 2 years than the first few. I have recently left my full time job as I was made redundant. Before looking for a new job I want to have a crack at full time share trading to see if I'm successful, if I'm not after a few months ill go back and get a Normal job. If i make money I would like to continue on with it as it would be a dream job for me. I have Iress etc ready to go. I have up to 50k to play with from my payout. My question is how much can I expect to make a week if I'm an average trader? I can read a chart and will use tight stops, I'm comfortable in my ability to make a few successful trades a week.. Is it possible to eventually make more trading than my 100k desk job?
Cheers
