An idea! An idea!

In the midst of writing my paper, I decided to go to Chocolate Fest. I guess the thought of chocolate itself starts making me think of creative ideas. One idea entered my mind. Since I am unable to get a hold of anyone within the geochemistry lab, and I'm somewhat in a need of extra money, why not start a dog walking business in the neighborhood? To me, I think it's a great idea. I can get business cards, print flyers, and talk to some neighbors who have dogs to see if I can get them as referrals. I found a website that suggested that I get some sort of pet walking insurance, but I think by having the owner sign a simple waiver will do. I will, however, ask the clients (should I ever get any and stick by this thing) if I could meet their pets first to be sure that we get along. I don't want to walk a dog that's going to be mean to me and anyone else on the street. Also, there's quite a few places I can post flyers and cards at in the neighborhood. That's a plus. Now, the only part I can't figure out is how much to charge. I tried looking for prices from other people I've found online, but I came up with entries that are more than 3 years old. I'm not trying to actually start a business. A little extra money in my pocket would be nice, and also meeting new people in the neighorhood would definitely have it's benefits. What do you guys think?
