New Show - Where to go for support?

Hello,

Long time reader, first time poster. I have an idea for a new traditional Irish dance show - I am a dancer myself and have toured myself. I know that this market is quite saturated as is, but I have thought of a niche that I am confident will be very successful and fresh.

I am at a standstill now. I was always the dancer, and have no idea how to go about approaching companies for support for this idea, or even what steps to take next. Would anyone know of any companies who I could pitch my idea to to see if they will support it? Or advise on where to go next?
