Independent Dispatcher as a career

I have a question about becoming an Independent Dispatcher. I have owned my own box truck and cargo van for gees about 22 years running expedited freight across the country. I missed everything my first son did now I have a 3 and 4 year old and don't feel like missing everything. I looked into an agent and a broker but would rather fight for the truckers and really try for both of us to win. I'm going to take a class with coverloads.com to get some experience with the actual ins and outs of the industry. I've dispatched my own loads and negotiated better rates over the years so im not 100% green.

What is the biggest obstacle a new independent dispatcher faces?
Is there truly a market for an independent dispatcher or is it going to be fazed out in the future?
Is it difficult to find owner operators that are willing to go with you if you are new as a independent dispatcher?
When you contact brokers off the load board are they just worried about the Motor carriers experience or mine as well?
Are load boards the only place a dispatcher can find loads or is there anyway to solicit shippers in the name of the motor carrier you represent?
Are there very few loads on a load board that pay any good rates?

I know its another hand in the cookie jar and all the other complaining that goes with it. Isn't it worth if someone truly fights for better rates and doesn't try to load you with junk? I mean %5 of nothing is nothing. Any input would be appreciated.

 

I don't want to be a broker or a freight agent I'm looking at becoming an independent dispatcher. Someone who works for the O/O to find them loads. I know the differences between them all and what they actually do but i am not sure if there is other ways for a dispatcher to find loads. Referring to using only load boards to find loads.
