Lol sweet developers  just the question I love to answer to you is that idea sounds great & would be fantastic 
2nd question is there already an app you've created and maybe already trying it out beta way on some of us gals here .... yes .....no.....maybe as you on the sly could possibly be doing and maybe if im wrong by 1s the above well then i apologize because then it will be a different reason my phone acts as if im a developer's playground theres reasons i say all 11q+qI can be your 1st tester of your new app but I also have a few questions to you as a developer if I wanted to be a tester like a true let ya know how things can improve by insight is there jobs for that like real live life jobs to get paid while learning too ?????
        
        
        
        
 Just a thought. Also tracking wise i just meant if its a map like structure.  If a hobbyist is in a time crunch i can see how knowing what providers are available close by would be beneficial, but it would probably be safer to have just a list and then it can be filtered by distance,rating,etc to get the best fit within a certain mile radius.  Also what I meant by boards/sites that a provider could link one ad to is maybe the top 10 boards+?
