Any thoughts or advice would be greatly appreciated.
Find a business similar to the one you wish to open. Speak to the owner and make a wholesale pricing agreement. ie: he gives you a discount and produces work for you that you provide to your client.
Go find customers and sell the services. If you can sell enough services for it to make sense to start providing the service yourself then grow into production.
If not, you haven't risked anything more than a lot of your time.
Whether you are great at video production or not, what matters is that you can generate enough sales for your business to be successful. Testing your sales ability 'in the trenches' is a much better measure of potential success than most market research I've seen.
