Basic IPhone and IPad App

I need an app for Iphone / Ipad developed with 4 different sections. These sections need to be updatable from a secure admin backend. The content of the 4 sections can be stored on a remote database. (mysql? I am willing to take advice on this) An example of a similar app is the Dublin Fringe Festival App. I will provide starting content once the project starts. I will need advice on where to host files etc. For my websites I use a Linux server with cpanel. Can I use the same hosting provider? I have a very limited budget for this but if I can find someone that I can work with there may be more work down the line. No quotes above $50 please
