I so want to start a business but I dont know what to do a business in

it all depends what are you conversant with and what is coming to you with ease

Notary public title signer its only one class, boom done! Great income $50,000 a year average!

Or contract with car insurances to go a charge peoples cars when they can't start their cars.

Or start a store of some kind like second hand book store, or bike store, or, second hand furniture, costs are low.

Or sell online (you can make tons of money selling online)

Web designer. Learn from an adult school in your town, 1 class.

Realtor, 1 class. And pass a test.

Appraiser, I think this is also 1 class and pass a license exam.

You handy? Home Reno’s are booming still.
