I am surprised no other hobbyists have answered yet, as there is usually no limit to the guys here that love giving advice.

Besides the previous suggestions, you may want to consider having an incall. Also, expand your marketing to OC and maybe even Inland Empire and LA.  

Book a date, write a review & ask a reputable provider to whitelist you here on TER,

the geographic area for marketing.  I'm an OC guy, but routinely go to both San Diego and LA to see providers that interest me.  Its often well worth the drive even if I have to start over with a brand new erection once I get there.  

I know its just marketing but that along with a hi rate can make it tough starting out. I would think you'd get more business by starting at a lower ask. Get some stellar reviews and then slowly raise your rates. God knows thsts a tried and trusted model.

Once you set a rate over $350 for an unreviewed provider, guys are more hesitant to take the risk.  $500+ is more in the range of well-established, well-reviewed girls that have been in the game for many years and have a loyal customer following.  Many top girls here started out in erotic massage only at $150 and worked their way up the rate scale as they added more to their menu, got good reviews, and attracted regular customers that they could count on to keep seeing them for full service.  The other consideration is that if a customer DOES decide to take a chance at your rate, he is going to judge you against other girls that have the same rate, so it may result in a less than stellar review if you seem like a newbie, whereas, at a lower rate, reviewers will not have such high expectations.  Bad reviews in the beginning can do more damage than no reviews.  The best way to assure good reviews anytime is to give good value for the money.  Avoid getting caught up in GPS.  As Warren Buffet says, "Price is what pay, value is what you get."  As long as they are equal, you will do well, but if the value doesn't match the price, you're going to get some bad reviews.

If your seeking TER reviews here offer the special for those who can submit a review. Once you get a review on TER your website should link to your profile.  I see you have no information on your site about you, so I would add more content.  Your stats to start with basic information, like your age & measurements.
