GPS My City

This iPhone-y business opportunity allows freelancers with "good writing skills" to design their own city tours by writing descrips, photographing sights, and recording voice narration; accepted tours get turned into apps and published on iTunes, with the author getting 50% of net sales, or $25 and 30% of the net. Existing SD action includes Museums, Gaslamp, Old Town, Cocktail Lounges, & Balboa Park, leaving over 100 virgin 'hoods -- if you pick Clairemont, definitely take the $25 up front.
