Improve on existing Sharetribe marketplace website

I built a marketplace website on Sharetribe that is currently live. It's fine but there are changes I'd like to make that I think require customizations I'm not familiar with and/or do not quite know how to do. The website is https://www.golflessons.co and it's a marketplace for in person golf lessons with golf instructors and golf students. Here are some of the things I'd like to change: 1) Search functionality. Specifically, if someone searches by Current Location it's far too zoomed in so no golf coaches are displayed, whereas if you search by nearby city names, there are clearly coaches nearby. I could be wrong, but having done some research, it looks like changing it to a "Point of Origin" search combined with a filter on distance would solve the problem. 2) Ensure provider payment systems are setup properly in Stripe 3) Provider onboarding flow. It's setup but I don't think I did it optimally. We can talk through that but will probably involve changing or updating user and listing types/categories/fields/etc. 4) Customer onboarding flow. Similar to provider onboarding flow, I think it can probably be done better. Willing to look at all proposals but will prioritize folks who specifically have experience with Sharetribe. Thank you!
