Hi providers.  
I am based in Los Angeles and offer incall to guests. I work out of 4 hotels that I rotate in Hollywood, West LA, mid-city and LAX airport area but the hotels are really expensive and I think renting an apartment for providing would be cheaper. If I had an apartment somewhere I could only host in that one area. Providers who have experienced this, would I lose three quarters of my business or would guests come and see me anyway because right now I see the same number of guests in those 4 areas. I appreciate it.

I couldn't resist so I checked your website.  Your Gallery page is empty?  No pictures?

In fact, I know some guys who would not go to hotels, only residences due to privacy and discretion issues so, in fact you may get even more business, but I know the traffic in LA is quite heavy, so you would need to be conveniently located right off a major highway or on a less congested area.
We have tons of "by the week" rentals here in Florida, maybe those exist in LA as well, I would say try it for a week, then if it works you can progressively make the transition between hotel and residences.  
Also, keep in mind that you have to keep your traffic low at an apartment or high rise so you don't raise any red flags with neighbors, concierge etc..

When I did this very same thing I had 3 locations all in different areas of the city (New Orleans) and it worked perfectly for 6 years. They were shared locations and we also offered a driver service for guys who did not have a car, or who would probably get lost. I would ask around LA and see if any other ladies would be willing to speak with you, or even someone you trust to share expenses.
