Hi there!
It sounds like you need a lawn care guy. I'd be happy to help you sometime this week.
I've been doing this kind of work for a long time. While I eventually moved on to freelance writing and tutoring, my first job out of college was as a member of a landscaping crew. Later, when I moved out of state, I supported myself and managed to pay off my loans by acting as a kind of one-man lawn care business.
Most of what you've listed looks fairly simple. Do you happen, by any chance, to have a hedge trimmer? I have a weed whacker and some clippers, bags, and other tools. Looking forward to getting started.
Chris
