**What's the average (approximately) cost to open a basic LLC in Florida state or in NY state?** (FYI in my case is to buy an house in Miami and rent it. I already have a bank account in the U.S.)

**What's the average cost to maintain it?** I mean accounting + bookeeping + tax filing costs, etc.

Side questions: 

1. If I come to Florida or NY state., where do I generally have to go to open/maintain an LLC? Here
in Italy we usually ask a CPA (Certified Public Accountant) /
tax advisors. Where do I look for them? On the web? What do I need to
look for: "CPAs" or "Tax Advisors" or "Lawyers"?
2. How much paper work do I have to do every year to keep my LLC
running? Do people in US usually do this on
their own, or do they go to places like lawyers or CPAs to manage
the LLC book-keeping/accounting/tax-filing and all the paperwork.

(**I
would like to be sure I do not make errors. I don't want to end up
in jail just because I forgot to pay taxes or added nondeductible costs to the economic income.**)

For instance: I have a small company in Italy and every 3 months I
have to bring cost/revenues invoices to the CPA. The CPA registers them
and at the end of the year he does the tax filing. So basically he
takes care of all the paper work/accounting/tax-filing, etc.
