I created: http://skitrails.info/ I'm an avid cross-country skier, and traditionally daily trail reports are done by hand by the maintenance staff after they're out all night working on the trails. I had the bright idea of putting GPS tracking devices in grooming equipment and creating the "what's been groomed" report automatically, in real-time. It took about 4 seasons to really get it right, and there was no apprec…
I looked at your website and don't really understand how customers start using your site and how they pay you. Do you sell them a GPS tracker and show them their GPS logs in an online map maybe? If so, I'd make the selling of the GPS tracker more obvious. You can also do customer testimonials.
The "customers" are ski area managers, they pay me to publish their maps and generate their trail reports.
The sign-up process is slightly obtuse on purpose. Because I'm still busy developing the site, only the really motivated customers actually contact me (via the "Contact" page), so I don't have to spend too much time doing a sales pitch that goes nowhere. I'm fortunate that I have a decent runway to play with.
I'll change that a bit this summer once I'm no longer frantically building out features.
There is effort required on my part for each sign-up, mostly around cleaning up GIS data that new customers supply, although I do supply a backend with tools for map management. The ski area managers are often extremely non-technical, and like the personal touch. I charge a modest premium for that.
