After Effects CS3 Popup effect

Hi there, I hope everyone s well. I know After Effects very well, however I'm having dificulty creating a certain effect I need for a small project. Basically, the idea is a 'pop-up book' style composition, things popup like a popup book, the camera moves in to reveal a different scene, pulls back to reveal another popup scene (4 in total). Currently I dont actually have any images for this project, however rough place holders (even just coloured squares) would be enough as I can update and add more elements later, its really the comp that I need. Can all the temp place holder images be actual comps themselves too, the reason why is that I may have to animate small sections, and if everything is a pre-comp, then thats not to tricky to update. I've found an example of exactly what I'm after (however, dont worry about the 3D at the start, thats not what I'm after, just the pop-up style effect). [login to view URL] As always with my projects, this is a no-budget project, so all I can afford is $30 (sorry about that) and won't be able to accept any bids higher than this (again, sorry) - but to someone a little bit more experienced with After Effects than I am, hopefully this wont be to tricky, and although the budget is small, it would be a little extra pocket $$ for you. The project will need to be HD, 25fps and using After Effects CS3 (unfortunately that the version I have, and I've not been able to buy the latest version for a while). If you could send me example of what you have done, that would be great. Many thanks, Chris
