I have my ongoing business and it gives good income
Also where I live it's not easy to work on tech and I can't leave my current business
How can I make a company for that without me in it?
In order to know more you should really talk to a lawyer about it. I assume there are intellectual property lawyers in your jurisdiction. You could try looking for an intellectual property lawyer who has done work in a similar area as your patent. If you can't find any by searching yourself, you could ask the lawyers you do know to help you. Once you have a good intellectual property lawyer talk to them and ask them for guidance and next steps.
I think what you're asking about is really more complicated and important than what should be settled by forum comments. You need to bring in a professional if you're talking about amounts of money that would be meaningful for you.
