Danny has a good point!
Big difference between cooking on the patio, and "being in the business". Starting a business, ANY business is tough. Most restaurants operate on a 3% profit margin. So your $1,000 catering event will result in a $15.00 profit for each of the 2 of you after working all night and half the day.
Get involved with your eyes wide open. Don't overlook Location, Location, Location.
Here in Texas, BBQ is abundant!! Heck even in Anchorage, AK. there are currently 22 different locations listed (I checked). In NYC, there are multiple festivals for BBQ some of those have over 25 LOCAL teams, and that doesn't even count travelling teams (I checked).
You might be the biggest hit in your town. How about moving to Nepal and open a location?
Next, you need to comply with the sanitation laws, and be trained how to NOT make someone sick, and how to keep your catering business clean and sanitary.
Competition is a good thing and can establish whether your product is world class and establish a reason to actually open a restaurant or business.
If you are completely dedicated, and have the financial resources to be able to pay your rent, utilities, equipment bills, food bills, gain a customer base, work long hours 7 days a week, sweat and fret over what others are doing that can destroy your business while you are
not there pinching pennies, and still not go broke then you can probably do well.
Having family support is also a must if you have a spouse, children, heck even a pet that needs attention. If the homeboss
isn't in the mood to financially support the new "career" the problems will start early and be frequent.
Most of us find the obstacles stand in our way, and will never be at the level that the Johnny Triggs and Myron Mixon's will be.
But if you can beat them at their own game, knock yourself out, and tell me where you will be located. I wanna come sample some world class "Q"!
Honestly, Good luck to you!!!
