Hi James,
Been a long while since I last looked on Freelancer but your project caught my eye as on the face of it what you are asking is very straight forward for me to achieve accurately and in the format you require. Although I work using lots of video editing and compositing software I do tend to predominately use Adobe and so creating the file in After Effects is no problem!
Obviously you don't mention how much text or how animated etc. you want it to be for example in your description but regardless it shouldn't impact on the time or cost of the project from my end.
I have produced dozens, if not hundreds of dvds and videos that have required captions, titling, animated menus, overlays etc so whatever your actual requirement is I am confident that I can give you the result you want quickly and efficiently!
I have put my bid in based on a day's work but if it is less than that I would be happy to accept a lower amount.
Thanks for reading and good luck with your project!
Andrew
