Only asking for £4 for Z-Cards.
£4 per month for as long as you subscribe to the service.
This doesn't appear to be a model agency in the usual sense - what you pay for is having your picture on the site and a subscription to their "castings" service. They don't actually represent you or actively try to find you work.
Interestingly, one of the "clients" listed as having been casting for models is an online magazine based in the USA that as far as I know doesn't pay anybody for anything.
Here's a list of reputable real agencies

That's not to say this is definitely a scam but if they're not on the list then you should exercise caution, especially when you have to pay £4 per month just to be on the site and receive an unspecified number of 'castings'.
