I been at this for almost a year now. I've had quite a few sales but haven't come close to breaking even yet. That is probably a bad thing
I'm going to hang in for a few years though and see what happens. I think the ones that make the "big bucks" are the ones that have been around a while and work really hard at it. So after a month I wouldn't be discouraged. As many people have told me you have to keep building and submitting!! Good luck to ya!
