IOS and Android Mobile App Development

Hi, I am looking for someone to build an app native on IOS and Android. I have the layout on how I would like the app to be as I had someone start the project but did not know what they were doing. Budget is flexible for the right person. Will also need a website built to coincide with app on the second stage. Would ideally like it to be completed in 6 weeks. If you can help let me know. Thanks.
