I would prefer not to open a conventional bank account if I can keep things simple.

@Natalia DavisI’d just keep it simple and collect cash.

Try to always remember and apply the KISS principle (keep it simple). 

However, a personal financial statement can give you a clear picture of your assets, liabilities, and net worth, which could make the loan process smoother and quicker.If you’re not in a rush, you might consider setting up a simple personal financial statement in a spreadsheet.

From an income tax perspective, the LLC provides you with absolutely no benefit.Even from a "anonymity" perspective - if that is a Single Member LLC, the K-1 from those syndicates is still required by the IRS to be issued directly to the beneficial owner - you.If you don't make it a single member LLC, say your spouse is also a member, now you have a partnership tax filing - if it holds a number of LLC interests, it is now a partnership filing that is a pain to file to roll all of those activities in and report it on to your personal returns.In short...most likely it is best to keep it simple. 

The math on this is simple as others have alluded to.

SIMPLE!

I'll just ask a simple question....

Some things in life are simple, and this is one of them: If your business plan depends on dishonesty and concealment, then it is wrong.

Many services offer this, a simple google search should find you a firm.
