This is only a suggestion but what if other people post thier lets play on the website aswell so then the website would be known for its awesome letplaying cos i havent really come across a site were its only lets plays.
GameAnyone.com is a site dedicated to let's plays and walkthroughs. It's really good and I encourage you to check it out.
I've actually started (again) on site development. I just end up throwing out what I've done, I'm not a perfectionist but you wouldn't think it with the amount of code I've thrown out.
