If I understand your situation correctly, I would like to make a few suggestions to make a ‘few bucks’ to support your photography ‘habit.’ Start where you are with the equipment that you have. It appears that you have the 30D. It that’s the case, you have more than enough to get started – that is, if you take quality photos (I know that the 30D does – sometimes we photographers don’t practice enough to use it to it’s full potential. So, I’m assuming that you can shoot and produce very good images.
Here is a brief version of what I suggest to other ‘budding’ photographers like yourself: I live in Southern California where a lot of people have dogs that they walk regularly. I tell the photographer to, first, make sure that they have an online presence – preferably an online gallery where they can provide a website address to people. Then, print some business cards (this can be easily done with an inexpensive inkjet printer) with the photographer’s contact info and the website address of their online gallery.
I then suggest that they take their camera and position themselves somewhere where people walk their dogs. As the people are walking towards them, I suggest that the photographers ask the ‘dog-walkers/owners,’ “can I take a picture of your dog?” It’s a numbers thing, but quite a few will stop and let you take their pictures. Most will ask what the picture is for. The photographer replies honestly – “I’m a photographer, I like to practice to stay sharp, I always have to keep my portfolio ‘fresh,’ and you and your dog offer a great ‘kodak moment!’ Usually, what they’re asking is different from what they really want to know, I’ve found. What I’ve found that they really want to know is “are you trying to sell me something?” and “how can I get a copy?”
If they give you permission to take the shot, do so quickly. Fire off about 5 – 6 shots (I’ve found that if you shoot fast, you can get off 5 -8 shots in 30 – 45 seconds), sincerely tell them “thank you,” and hand them your business card (with your contact info and online gallery address) and say to them, “you can see the proofs by tomorrow morning in my gallery.” This process shouldn’t take longer than 30 seconds to 1.5 minutes (the longer periods usually are from a lot of questions – in most cases, these will be your 'long-term' customers).
You can price the photos how you want. However, I suggest that you price them low ($3.00 - $5.00 for a 4x6, etc. this part is also dependent on the online gallery company that you use). I suggest a low price because people usually buy photos of their pets. They eventually follow up with you and ask you, either to take portraits of their pets, take portraits of them and their pets, or take portraits of them. It’s a multi-step process. But, it shouldn’t cost for anything except the materials for the business cards and the cost of setting up an online gallery.
I’ve gone through this effective strategy rather fast so that my response wouldn’t get too long. But, I hope it gives you some ideas. You should also take the advice of working with an experienced professional. But, if you’re looking to regularly make a few bucks to pay for your photography equipment and stuff, try this suggestion – or a variation of it. It works – I promise!
I hope this is helpful.
