Thanks to digital the business & hobby has changed & a lot of people think they can earn money by charging for their photos, especially by doing weddings since that's the one market we know is looking for ways to save money. It's also the most demanding market & you only get 1 chance to get it right, PLUS you'd better know Photoshop inside & out, & have a thorough understanding of the rules of exposures, DOF, & lighting etc. You'll need better lenses, a back up camera & some other photography equipment but you'll also need a good computer & calibrated photo grade monitor & either a very good printing service or your own high quality in home printer. If you're even remotely serious I'd take a photography course (night school or full time) PLUS devote lots of time to Internet forum research on your chosen interests; AND I wouldn't quit my day job.
If on the other hand you just want to shoot some stuff for friends & family for a modest fee you'll still need a thorough understanding og DOF & shutter speeds, & apertures PLUS post processing & printing. I'd also recommend a back up camera & better lenses to start with. Things can look pretty good on a computer screen but that doesn't mean they will look GREAT when printed.
