Roy, I owe you an apology.
After doing some thinking, I realize I am completely wrong. With my following advice you can quickly go from shooting your family, to making money in very little time.
With your budget, you can easily get yourself some excellent equipment. Learning the technical aspects of exposure and lighting are really fairly easy. It will take a little time till you can pull off consistent results, but once you do, you are ready to roll.
1. $elective color sells. The general public sees selective coloring as some sort of magic. They love it. You don't even need to know when it works best, or when it actually detracts from the subject. The general public won't think twice, they will love it. Trust me.
2. Green Screen. Get yourself a green screen. You will save a ton of money on back drops, because there are DVD's available with thousands of ready to use backgrounds. Simply select out the background and replace with a background from the DVD.
3. Collect poses. Look on the internet at well known, and pro photographers. Print out poses you like and put them in a book. Organize them in categories such as maternity, baby, engagement, senior portrait, etc. This greatly reduces your learning curve, and you can easily produce images such as those by Anne Geddes. Your clients will be amazed at your talent. Never stop looking at others work. This way you can keep on top of current trends, and appear to be on the forefront, rather than just following the pack.
4. Props. Get yourself the standard props for various shoots. You know, things like baby blocks to spell out babies name for a maternity shoot. That is tried and true, a guaranteed seller.
5. Pricing. Don't price yourself too low. Word of mouth about your work will spread like wildfire. If you price yourself too low, you will have a hard time raising your prices, because the word of mouth customer already knows you are cheap. On the other hand, don't price yourself too high. You want to bank on undercutting the pro.
In your original post, I don't get the feeling you want to turn this into a business, but, I guarantee that if you follow the above advice, you will have people knocking at your door in no time.
Again, I am sorry for my rudeness. You can do this. Just get comfortable with the technical side, learn to nail your lighting, and the rest is a cakewalk.
