I wasted the journey into London. Then was told I needed to pay 350 pounds if my photos passed their approval to go on their website (which I would have to upload myself)... and then wait to be selected by their client's. Luckily I didn't have that kind of money to part with in the first place, but they won't tell you anything like this in advance of the visit. They wait to rope you in whilst they've got you "in that visit"
