It depends a lot on your personality and the quality of the content you would create. Who is your target audience? Men and women tend to have slightly different preferences/ focal points. 
If you started one, I might subscribe at least to check it out for the first month.
Right on. I guess I would have to research these things then. 
Would probably have like some sample vids of me doing this or that. Then have rates for special  requests? Idk I guess I've never thought that hard about it. 
Any suggestions?
