As a symbolic designer and illustrator, I would suggest that the best style to do what you want done is to use Adobe Illustrator & Flash (for the animation). If your handy w/ software and swot swiftly, you could pick up on these honestly very well, however it may not be worth the time or money to do that. I'd consider hiring a designer who know illustrator and flash to implement your planning. If you thoroughly explain your project, and sketch out what you call for done, any pro lofty characteristic designer would know how to do this for you. Every designer is priced differently however, and hold different design intrinsic worth, so you may want to shop around. :) If you have need of any further proposal, please consistency free to contact me.
Unfortunately, I don't know of any low cost impressive programs, as I single work next to professional software programs.
