I suggest for quick impact choose unique name for domain name, or you will be in my boat i’m in constant battle with the big G for months as my domain has casino games and lists top 3 searched names. Though I’m gonna stick it out and eventually be worth it, for imediate impact i’d go with a unique name that you wont be battling keywords to get yoru site to come up.
Also yes youtube is good i found some good results already.
