I generally charge a smallish flat fee for what you described which includes the operating agreement, a kovol letter with your accountant, and education about how to make sure the limited liability stays limited liability. 

What are the typical fees (flat vs. %) and services provided and what would be complimentary extra services?  

If your providing agents leads as flat fee and maybe % of completed sales...But if you have a degree, it's not hard to get your license

I've been a longtime lurker, but this is my first venture and post, really need help/advice.I've been under contract to purchase a 2 flat in the Jeff/Portage Park neighborhood of Chicago, it was a not approved short sale (we have now received approval, we have 30 days from today to close)It's a standard 2 unit masonry home, with finished basement with an illegal unit, and a recently renovated one unit, other has original finishes w/ new carpet. ~1000 sqft each unit 2br 1ba.

Prices in CA have also gone down and stayed flat. 

We charge a flat fee of $1200 for a closing.

On my out of state properties I pay a flat 10% and we've been able to build a strong and productive relationship.

Prices are general flat yet many flippers are still overpaying.

@Jen SimbolwFor stoves, go with coil burners, not smooth flat top.

If you feel it to be a bit awkward or could become a conflict, see if she'll pay one of her associates a flat fee of $500 or something to represent you (basically take care of paperwork)  for this one deal..
