I need to pay taxes, help! & want to share an incall in Chicago and NYC

I'm in need of an accountant to help me legitimize my business. I need to be able to legally work in Illinois, New York, and other cities pending. Help all the way from applying for a business license, to paying taxes, to deductions, to all the paperwork I would need to finance stuff and show that i am legally working with ample income.

Also looking to bounce back from New York and Chicago without paying a ton of money for a hotel, so the option to split an incall with a provider would be great.
