Thanks for your question, Juan. It's obviously very hard to start a company while you have a full-time job. But I think entrepreneurial ventures are so exciting and can be so fulfilling that you should go for it. Your first goal, should be to craft a powerful 2-3 page pitch on the business opportunity. It should describe your strategy in the entertainment industry, the sectors you're targeting and the size of those markets, your background and how it fits with that plan, the competitors in the sector, the risk factors in the deal, and the summary projected financials.
Many people believe they have to write a long business plan to attract capital.
But I believe in exactly the opposite, which is if you can not lay out a compelling arguement for the company in 2-3 pages or less, you will not be able to layout a compelling arguement in 100 pages. So put together your best 2-3 page pitch and show it to one of the regions many incubators or angel funds. If you look up those terms on the web, you'll be able to find many potential investors. If I've been even a little bit helpful to one entrepreneur then it's been a big success for me. My one overriding comment is that there's nothing more exciting than starting a company and there's never been more capital available in U.S. history to back good ideas.
