Black Box Management

Hi All, I am looking for some advice.............. I was recently accepted on to black box management WA's books and was wondering if anyone knew anything about them? Are they a good agency, do they get allot of work for the people on their books, is anyone with then or know anyone with them that could help me? You see when the called me and accepted my application i was then told i needed to pay $150 for an online profile and then $8 per month to keep it running. They told me this wasnt a joining fee as they just take a cut of whatever job they get you. In the package that i read before applying it mentioned about and online profile but worded it as 'if you need help with one, this is what we offer......' i personaly dont need help with one as i have my own website, and dont realy see the point in me paying out that money, plus i know all to well that you shouldnt pay for an agent! I dont know wether im being too suspicious/cautious, and this agency realy are good? So could anyone help me with this matter? Thanks, Michelle. :)
