Actually I suppose I don't live in the right place for a lawn care business either. Except with this, if I can schedule a few properties in the same area, there won't be so much time wasted in traveling. Errands never really worked out that conveniently.
One big drawback to the errands was grocery shopping. People can get very specific with particular brand, flavor and size. Believe me, you can spend more time than you'd think trying to hunt them up. I had one customer who was extremely picky about almost everything her list.
It's funny but the business consultant I worked with felt I'd fail because I had too much competition. Companies 1-3 hours away from me. I called most of them and they thought it was ridiculous.
If anyone is interested in starting an errand service, I'd suggest a flat rate for things like grocery shopping-because it's not as straight forward as it sounds. Just go pick up a few groceries. I would also suggest that you get enough cash ahead of time to more than cover their purchases (returning any change when you deliver the groceries). You wouldn't want to be stuck with those bills.
The one thing I wish I'd focused more on was picking up food from local restaurants and taking it to the customers. I think THAT would take off very well in many areas. As long as the charges weren't astronomical. The only things you can get delivered in my area are pizzas and anything those restaurants sell (like subs, breadsticks and salads). I think it's that way in many cities. You could probably even get to know the owners/managers and enlist their help to market to customers. It would mean more business for them. And they would probably be willing to let you supply tasteful paper placemats for them to use, as well as putting business cards somewhere in their establishment.
I should add that I think placemats in restaurants are a good idea, no matter what line of business you're in. It helps owners/managers to cut down on their expenses and gets the word out about the service you're offering. It would probably work better in non-chain establishments though. You'd have to Google it because I can't recall where they can be ordered.
Sorry, I tend to ramble. A lot!
