Thanks for your opinions.
Movieman - your as encouraging as my husband. Can you please expand on your answer?
I actually have the plans in works to do what jrossjr suggests. I'm going PT at work. I am going to give this a shot. I have been thinking about it so long - I have to give it an honest try.
Wish me luck! And I'll keep you posted.
Sounds like you have made a decision, and certainly PT is a good idea to begin.
From your initial post the following things came to my mind and that's why I said "no".
1) Immediate loss of full-time job money (if you quit altogether).
2) Initial returns would not meet what you said you cleared at full-time job.
3) You didn't mention anything about having vehicles to to the work with.
4) You didn't mention who would do the moving of stuff.
5) You didn't mention where acquired stuff would be kept until sold.
6) You didn't mention if husband was working full-time.
7) You didn't mention if health insurance was a concern (two kids to consider).
Other things I probably haven't thought of in the moment.
It just didn't sound to me like a good idea considering what I knew about your position, but IF, I repeat IF you have the chance to go part-time AND, I repeat AND you could go back full-time, then that might be another story.
With your children active and needing transport, care and feeding, this business might get in the way more than you think. It would not simply be substituting one 4 hour block a day (at the 2nd half of your full-time job) for another 4 hour block a day. If you have an 8 hour work day now it's hard for me to imagine there would be the chance for floating work time there when you consider that auctions happen typically from about 9 to 3 or so during a typical day.
Anyway, that's the long answer to my short answer "no".
