Specializing?

I'm in the 'paperwork' stage of starting a limo service here in Sarasota,Fla. I'm starting small with one vehicle yet to be purchased. I'm wondering if it is a good strategy to specialize in corporate/executive business. That means a sedan instead of a stretch, and less start-up capital. But will I lock myself out of the business I need to grow? Suggestions, anyone?

From what everyone is saying in the forums, it doesn't look like you will last a long time using a specialized service to start off. It seems that it's harder to find business when you specialize and decide not to use the regular stretch limos.
