What would be the best photography business for me?

I just graduated in Fine Arts – Studio Photography – I did plan on obtaining a masters in art administration; however, I had a baby in my last semester and that plan vanished. I figure my only option with a new baby and three other children is to start my own business. The problem is since I studied as a Fine Art student my knowledge in digital is very limited. I always had a point and shoot digital and I received a SLR digital a few months ago. My knowledge is growing everyday but I also need to learn color because I’m use to black and white film.

My current (very simple) plan is the following:
(Background knowledge: I do live in a enriched art community – I do not have a lot of money – current equipment- film and digital SLR, clip lamps, white and black cloth backgrounds and no studio just a area in my house)

The plan. Starting out I want to sell my work on the internet and outdoor art markets. In addition,start to take outdoor photos of children, single adults and couples. I do not have expertise with weddings so I’m nerves about that.

Question – Do anyone have any advice for me? How to get started on a small budget? If the plan is going in a good direction? If I should look into another direction? Equipment I need to buy the is not expensive? Advice on marketing is needed. Feel free to give additional advice.
Thank you!

From my experience, it’s possible but it’s going to be hard and grueling. Photography is a job with hard competition, you have to be extremely good or extremely original. I’m not saying you can’t do it, just keep that in mind. The best thing I can say is to get involved with social networking sites(ie. Myspace, facebook, DeviantART, redbubble modelmayhem etc.) and promote yourself through there. It won’t cost you anything either. You can also sell your photos through deviantart and redbubble but its hard.(I’ve only sold 1 print through deviantart). Modelmayhem is the best way to go if you need models to start off with. They will work for free a lot of the time.

You can also make cheap fliers if you have an understanding of photoshop, print them out at staples or something, not too expensive. post them around town. (not sure if that’s illegal or not where you live though haha, it is here)

As for equipment I’m not so great on that… I’d say start off with some cheap studio equipment, a softbox or photography umbrella. The backgrounds will be good. You can also depend on the natural areas around where you live for photography, (that’s what I do and it works pretty nicely).

You already have a good camera though so that should be all that’s really necessary until you build up a portfolio. just be resourceful and use everything around you.

I hope that helps. I’m not an expert on studio photography, I mostly work with bands and models in the alternative scene(music, underground, metal scene) so I mostly do conceptual/themed shoots and I take pictures at concerts for bands as well as promo shoots. I’m also a photoshopper.
Heres a couple of my pictures if you care to take a look hah: http://i222.photobucket.com/albums/dd10/your_maja/efde2a5ef5af65482763a18ba38d19ca.jpg

I hope that helps you out! My style is probably way different than yours though so you may have to take different paths to get to your destination of your self owned business. Good luck though!
