Hey Joey, chin up mate. I've not been in this exact situation, so I am just brainstorming here from things I have seen others do...... Have you tried a new advertising site for a week? If you are not known on a site and it receives a lot of hits, you surely get more interest when you are new blood. The only trouble is, perhaps you have to go to a big established advertising site for this to really work- one which if it is that renowned will require payment to advertise. BUT worth a shot if you think it will work. Also, bear in mind that you would be better off appearing new on a directory at the very end/beginning of a month when people are just about to get paid/have just been paid. New enquiries always seem to pick up for me at these times anyhow.....
Secondly, have you thought about offering, say, 90 mins for an hour rate for a limited period, or, say, offering a week/fortnight of discounted rates and plugging it heavily on directories you list on/on your website, rather than slashing rates for good? This is might work to make punters think they are getting a deal so to speak and make them book you that week if they know it's for a limited time. It may also increase interest of those who might not have thought to meet you before, but who will hopefully love you so much they will want to keep on seeing you and be happy to pay your higher rate when you raise again at the end of the week/fortnight whatever.
AND, finally, doing this it will get some interest from people who might only book you when you are at a lower rate, but hell it's quick cash if that's what you are after, and if it gets some dosh in to work with in terms of paying for future advertising etc to maintain levels of interest, then it could be worth a shot. This is only if you feel comfortable doing this though, if it feels demoralising to you then I would advise against it for your own sanity.
Just some thoughts! xxx
