I have been using an app called filemaker go to run my database on my iphone. It runs well and i have been using it for about six months, however it needs tweeking to make it run extra efficiently with more features and to do this i need to get in a professional which would cost £6k. They basically would take my database and start over adding any features that i or others involved requested...i am not in a position to fork out that amount of money on my own, so had a brain wave that if i got interest in the idea then we could all club together and we could then all use the end result.
I have spoken to the design company who would undertake the management of any payments and support, i would be just the middle man with suggestions!!..............any interest?
Go and have a look at the basis for the database........................
