Affiliate Marketing Secrets

I am in the process of starting my own business as a virtual assistant my niche will be General office support, Bookkeeping, and maybe real estate now im having a hard time getting a name and suggestion?? but also once i find the name do i first register it or get a domain for it ? any suggestions would be great : )

My friend keeps telling me to not bother where the competition is not only high doing this but CPA’s start up bookkeeping businesses with tax experience have a huge edge not just in education but experience and why would they give me their important financial info. I said to get experience in quickbooks I would by it for myself then take a course at a community college first in accounting principles and a QB/payroll course. After that work 6 mo. /1 year for a bookkeeping company if they would take me and then try to start doing freelance? Does it not matter if your a cpa or very experienced or if you are not then are you just wasting time if I have nobody as a figurehead with lots of expereince and then that way they I can get customers? Also is there a way to niche this? My friend said his wife is a controller and left the bookkeeping company because they constantly had competitors poaching their clients and that would cut into profits so argh ! Any thoughts Please! Thank you for your suggestions:-)
