I´m an experienced programmer specially on what concerns to database. In this project, all the apps ( iOS, windows, android etc) are just front ends to the same database. I would be pleased to develop the database, all the needed queries, the apple (ipad iphone) applications and all the interface elements. The others platforms could be bought for very cheap since i would provide all the elements i just mentiond. As it´s not my expertise area i´d rather not develop the windows/android applications. But again, with all the above mentioned in hand, it should be very easy, quick and cheap to develop those applications. Cheers !
