In my opinion, your conclusion is wrong--it is not the ladies who are going to give you the best advice. It is guys who are going to be reading your reviews and deciding if they want to pay to session a gal passing through town.
Thirty days at $30 is cheap compared to travel costs.
You have a limited non-GFE menu. The guys to whom that appeals (often those with spouses or SO's) may be more likely to stick with local gals with whom they have a comfort level.
Having VIP will allow you to search the database for menu items, just as guys do. You need to have a feeling for what your potential competition in a particular area provides.
FYI:
1) I have never sessioned a gal passing through town who did not provide full service.
2) Your profile items are "fixed" by your first reviewer, unless later changed via a "problem report" or contacting TER. If you expand your menu from what it was in August 2012, you need to inform TER.
3) Since you won't be able to figure out in 30 days what I have concluded from 12 years of reading reviews (the below #'s do vary by geographic areas):
A) By age 30-35, probably 80+ % of ladies with reviews here provide BBBJ. Around 30+ % also provide CIM.
B) While many ladies in their 20s provide only CBJ, an increasing number (in my area) are providing BBBJ.
There may be some ladies who have expanded their menus who would be willing to post how their business changed.
If you did not make enough on the road before, why do you think it would be any different the next time?
