I see someone else has a Bank Of America account too.
To the thread starter is that $4k in total income or pre-tax profit or what. One could make $100K a month but if his expenses are $99K well then he's not doing any better than someone making $2000 a month with $0 expenses.
Also some people do this part time as extra income. If someone has a $40K job and does this a few hours a week and brings in another $1K a month he isn't doing that bad now is he/she?
