Scouted by modeling agency- scam?

got scouted by an agency on oxford street the other day, 2 days later got a phone call saying they like my image and would i be interested in working for them..asked questions such as do i have any experience..(no)..acting..(no)...can i dance..(no)..but they are still interested and feel i have potential! Then ask if i have any professional photos i could submit for my portfolio..of course i don't. so she goes to speak to her manager for 5 minutes to see if they can help me. she is so pleased to let me know her manager likes my image so much she will fund my trip to an exclusive photographic studio where they will take my profesional photos, do my hair (toni and guy) and make up (Mac). i just have to pay for the copywrite/ ownership of my images which is around �70 for each image (4 0r 5 will be required.. so i'll be paying around �350). checked agency web site..very good, but couldn't find the studio on web. Letter from both institutions came in same envelope, same frank.... scam?
