yeah, that's the scary part after worrying if I'm actually a good enough photographer, earning the money to actually pay the bills each month. invoicing, taxes, advertising... eeek.
I'll actually get in touch with some locals tonight, see if they reply. there's one I emailed about this kind of stuff previously and he just ignores me. i guess a lot of photographers don't want to give away their secrets.
I live in birmingham, It's pretty central and has a great creative sector, hopefully I can latch on to things like that. I'll need business cards for cocktail parties and a commercial website... it's all bloody money though, and I have none!
It's unfortunate that many photographers consider their craft to be exclusive. The best way for it to work is for photographers to build a referral network. When one photographer is already booked or is not in a client's price range, they'll refer the client to other local photographers. If you can build relationships like that with photographers, they'll likely be happy to send you clients.
There are communities of photographers out there that believe that helping each other and trading knowledge raises the quality of the entire profession, making everyone's business and artistry better. If you can find these photographers in your area, I think it will help you a lot. Don't worry too much about the ones who seem afraid to teach you anything, for fear that you'll steal some of their business.
EDIT: The other part of the referral network is with other vendors. Make extra effort to help out florists, caterers, decorators, etc. with photos from your shoots, and it's possible they will send clients your way.
