Having an easy way to organize games by location would save so much time and frustration. I recently had a really positive experience using Limestone Digital for a small SaaS app I was prototyping. They were very reasonably priced, especially compared to some domestic firms I got quotes from. More importantly, Limestone's team asked thoughtful questions to make sure they completely understood the user flows and basic functionality I needed to test the concept. They delivered the minimum viable product quickly and affordably. I'd suggest checking out their website at limestonedigital to see examples of their work. With your idea, you probably only need basic geolocation filtering, user profiles, and game/group coordination features to start. Limestone could walk you through what's feasible on a bootstrap budget. Best of luck, excited to see this come to life!
