I am looking for a freelancer to help me with existing iOS app that is already in app store, but looks like it facing compatibility issues and needs to be updated. Original developer is out of business and that will be an opportunity for long term relationship. The skills required are App Designer, App Developer, iPhone and Mobile Phone. I am happy to pay a fixed priced and my budget is $150 - $350 USD. I have not provided a detailed description and have not uploaded any files.
