That's very ambitious. I would think you certainly need to know what kind of support you can expect. First time theater is tough - venue, advertising, royalties, etc. I have seen a couple of groups start (on different ends). One started with an historic straight play, so that the wouldn't have to put out too much money when they weren't sure they could cover costs. It is in its fourth season and remains a small group that does quirky shows and gets 60 - 70 per show. It is a small niche, but because of how they do it they have the luxury of time to slowly build an audience. The other group had their inaugural show last summer- Miss Saigon - they will be doing only a summer show for the forseeable future. They were gangbusters on advertising and were able to get about 350 per show (we are a small market to begin with). Their theory was that if they wanted to get noticed they had to try something that hadn't been done here. They were happy with their turnout and are looking forward to next summer. The similarity of both groups is that they had a plan and knew what they were looking for and what to expect. You need to get your ducks in a row and know what to expect when you do it. After that the show/shows you will do will be more apparent. You say you like Disney - I would think the questions about how you tie in with local schools would be important to tackle along the way. Good Luck!
