Read the self help section...  read back on these boards...  Looks for tips on ads, web sites, pictures, phones, email...  time management without being obivious...
In advertizing...  besides the services...  my biggest issue is ladies who use the same pictures over & over.   While your face can be blurred...  the rest should be good quality & large enough to see easily.  A variety of views, dress & undress, so that it total the client can be assured of how you look.  You're not selling the steak, you are selling the sizzle!
Few pictures, few views, makes me suspect the pictures are not current.  

Be honest... provide the services you promise...  for the full no rush time you contract...  you'll do well.

Now, to focus on you. Harbor_View gave you some sage advice. Use this site to learn all the ins and outs of working this business.

Get a VIP account. That account will be golden for you. It gives you major access to important benifits of this site.

Maintain perfect bodily and oral hygiene for every clients, never, never ignore doing that or short circuit the process of cleaning before and after each client, your health and the health of other people may depend upon your discipline in that area.

Maintain your looks. If you were lucky enough to be born drop dead gorgeous or you are one of those women who even those not drop dead gorgeous have that air about her, maintain your advantage. Give up or limit smoking or too much tanning. Go to a Spa once a month to have your skin, hair and nails treated to maintain them in top condition. If you have and do those things and perform at a top level for every single client, this business will be very good to you financially.

There is no reason for you to become greedy. You seem to be going about entering this business the right way. Don't stop the process of learning and using what you have learned. If you apply learning, you will make great money, meet great clients and stay out of handcuffs or out of other tight spots. Never, never see any client without doing detailed verification on him, if he is unwilling to share verification information with you, drop him and move on to the next client, if you are good at your end of this business and have hotness, you will have men lining you to see you.

If you are hot, you may consider touring. The big east coast cities, except for maybe Philly, are prime working ground for providers. Don't be put out by rates at top hotels, you will make that up fast. Look for hotels that have good foot traffic and good access, hobbyists in the cities of your interest can provide you with details via PM.

Good luck and stay safe.

who offer good service for a reasonable rate do well.  Good luck to you.
