Hey GM,
Agencies (in any industry) tend to want to make a fast buck by supplying scarce resources to their clients. An experienced 73' skipper is worth a finder's fee and requires less effort to 'sell', a fresh faced fATPL not quite so.
Many specialise in contract work so you'd need to have plenty of experience to be of interest.
That said, if they suddenly get a requirement for a promising low-timer who'll come cheap and might even pay for their TR...
I've used them in the past and as long as you remember that, unless you've built up a working relationship with them, they are ONLY in it for the money and that, in some cases, you can replace the word 'agency' with the word 'pimp', then they may be useful to you.
Good Luck
