Hi,
This is prob something you havent considered but would work a treat for this kind of project.
I would go for a browser based experience using secure connection, html5 front end,php & pdfs content managment maybe sway animated gifs over .swf and msql backend as it would give you best cross platform compatibility for your digi copy. This would give excellent results especially budget and for records, printing and general updating. If i was awarded the project I would host your project for free for 2months on one of my servers i then charge £15a month to host and do general maintenance i would manage Everything! (i also use cloudflare for extra security where possible) theres no contract you can move to a new host anytime after project completion and i will supply you with all the files no catch,
Even if you dont use me feel free to pinch my idea :-)
All the best,
~TrUeZeRo~
