Not trying to offend, but your statement makes me think that you are not ready to trade full time. Timing should not matter, you should only trade full time once you have an identifiable edge.
At a minimum I would suggest having at least 1,000 real life trades. Since you are only trading part time, you should then use these stats to look at a full 3 months trading, and what your income would be.
i made that comment because in the summer time volume significantly dries up. i have been trading for 2 years now. i took 2 weeks off just to see what i can without interruption at my job. i can honestly say i have 2 unique edges. i said i might actually do it full time in july because this time might be different because people are hawking companies around earnings time.
