Hi Cleandog.
That might depends on what most people use for their search engine inside their devices. Most devices today (mobile/ tablet/ desktop/ etc) use Google by default, and as far as I know Google give HIGHER priority to LOCAL searches. But I think you're right, enabling your website to be viewable and also navigate-able in mobile devices should give you larger audience.
I can't help converting your website into mobile-specific NATIVE apps (Android/ iPhone/ etc), because that requires specific hardware and also ...I'm no app expert:) However, if you'd share with me a LINK to your existing website, I might help build a mobile-responsive/ -compatible version of yours with just html5, css, javascript/ jquery.
Warm regards,
Hendra
