How about an app or maybe a phone-friendly site? Your site is very nice but I think you'll gain more users if we can use this in our mobile phone. Also giving a free call to check on how this works can really help. People nowadays don't want to use a service without seeing it in theirselves that it really works fine.
You can use it from your mobile! We don't have an "App", but it should work fine on your mobile browser.. It uses responsive design and will look great on your mobile.
