Honestly, getting a permanent incall space was what saved me alot of headaches when it comes to hotel policies and trying to host. I was lucky enough to have meet a few people who graciously allowed me to use their place to meet my new friends. I usually made an arrangement with them and worked two days a week paid them 100 a day (9a-2p since I worked while they were at work) or 40 per 2 hours (if I was having a slow day).
I was able to establish a consistent schedule for availability which helped build up my clientele. It helped out alot from 18 to 20.
Hope it helps
