Based on your previous posts, it sounds like this is your first project, but correct me if I''m wrong. If this is the case, I would suggest that you and your development team work on a smaller scale project that you think could be finished in less than a year. In your second post you say that working on a 3-4 year project without a publisher is a wasted effort. This suggests to me that you are looking for funding. You could work on this "smaller" game next to your fulltime occupation, costing you just about nothing. Then, when you are done, you can pitch the game to a budget publisher of some sort (check out the forum FAQ), or sell it via the shareware distribution method yourself. Not only will you generate an income (assuming that a publisher accepts your project), you will also have a piece of work that you can show a bigger publisher should you eventually hope to go full-time and receive funding.

Put simply "less but better" is the way to go. Whatever you show should work properly and be of as high a quality as possible. Many of the people that will be involved in deciding if your product gets signed will have no understanding of development (marketing and sales people). If they see a crude demo they will assume a crude game. This film trailer.
