Business Help

[tb]

I am doing this 6 months now,
with a few minor interuptions along the way.
I have about 100 free sites and a few galeries out there in 3 niches.
I submit to approx 50 sites at any given time and 50% of them accept my submissions regularly and the other 50% off and on.
I keep tuning the submit list in order to maximize my acceptance rate.
I am getting plenty of clicks to the join pages but no sales. I work with a variety of sponsors.
My hub gets about 1000 uniques a day as well. What should I do to jump-start sales?
I thought by now that I would have made at least a few sales, but so far nothing. Any advice would be appreciated.

P.S. if you think this post should be in the newbie category feel free to move it.
