I don't see that. I feel it is much more professional to work on the business at the same time as the game so we all know where we stand and there are no problems about money etc once the game is released.
And lets be fair, just because something doesn't work for you doesn't mean it isn't right for someone else, or that it feels amateurish.
Yeah I wish more people would focus on the business side of things a little more. It's a bit unsettling to jump on board and do all kinds of work without a contract or anything.
On the flip side, lots of people start websites and "companies" for their games to look professional, but lack of content (like, well, the game) just makes them look even more amateurish, as Rory stated.
Anyway, sorry, I'm no artist, but posting more info and maybe screenshots or a video will help find you one.
