What local service can i offer?

If you were to go out and knock on doors and offer a service, what would it be?
I am in need of some extra cash, and I plan on making flyers and going out around my city knocking on doors and telling them what I do, my idea is to offer things that are easy to do, I don't have any highly skilled skills, I am just looking to offer simple things, such as dog walking, snow shoveling (I live in Utah), room cleaning, etc, what other services can you think of that I can offer?

Depends on how good looking you are

In the summertime you can also offer gardening, like mowing lawns etc. - Especially older people would appreciate such services.

I think moving services
