Job-Hunting- Job-Creating

Still no word from the place where I applied for a job. It's hard to wait and I know I should keep looking.
Been trying to figure out the kind of job, that I would REALLY like to do and it always comes down to TWO areas: animals or plants.
As for the animals, I had the idea ti become a pet-sitter. Don't have the animals at my house, but rather go to their houses and walk, feat or do whatever needs to be done.

The other idea is newer and our lawn service guy pointed me toward it. Garden Design.
You don't need a formal education and he would help me get started. I could design and plant and maybe even maintain, e.g. on a monthly basis. Work with him, when it comes to the lawn and irrigation stuff.

Both ideas are tempting and I am thinking about them. I wish, I could partner up with someone, but I know, I can do it myself.
It would help so to get some advise. For the pet sitting, I am in touch with a company that sells franchises. That be cool, but I don't really have the money to buy into that right now...

What would you do, if you had the chance to start your own business? What would be your dream job? Besides professional biker.... :D
