As XW5 says walk away now,they are basically asking you to pay money to them upfront and this is something you should never be requested to do. Also I've had a look at their website and there is something about it which doesnt look quite right to me.
The fact the guy spoke to you for 90 minutes means nothing, I once had an industry owner meet me, take my photos, out me on his website and then tell everyone who rang to enquire that I was fully booked. This industry is populated with some very dodgy characters and if your spidey senses are tingling theres a reason for it!
