Need Programmer for iOS Map App Development

Looking for a very skilled programmer in the following coding languages:

- Objective X
- PHP
- My SQL

We have a fully developed iPhone App similar to Waze (not quite as complex, but similar) and are preparing to launch and have lost our programmer due to illness.

We need a programmer to make final tweaks on the existing code, as well as start work on up coming changes to the app. It is critical that the programmer will need to work with the existing code we have.

Initially, we just need the one programmer, but will need to scale up as we move forward.

Thank you

Michael
