It is all about how you market yourself. Your assumptions are not all the way true.

Be honest and focus on you. Monitoring other ladies will only bring you down. Specialize in what you do. Don't lower the bar cause other are and don't raise it for that reason either. If you raise your rate or lower your rate let it be because your business needs it or because your services deserve it. There will always be different price brackets of ladies. You decide where you wanna be and where your business can be successful... Nobody can decide that for ya... And its not based off of size beautiful. Simply how you market yourself and how your treat those who choose to see you!
