Mobile app for Driving Startup

I’m looking for an experienced mobile app developer to create a mobile app for my driving startup business. The app should be available on both iOS and Android devices and include a GPS tracking feature. I already have the content ready for the app, so it just needs to be developed. Of course, my budget is limited, so I’m hoping to find a developer who is skilled at creating quality yet cost-effective apps. If you have prior experience in developing mobile apps with GPS tracking features, please let me know. Thank you.
