It all depends on demand

Call the local tv stations, ad agencies etc. to see what thier regular demand for what you offer would be.

That will give you a good handle on the demand in your location of choice.

Once you have found that there is a demand, then send out your studios' promo-pack including what you offer, your reel (VHS), and how you can be more cost-efective than "the other guy".

That's how I would start
