I bet you could hire a young landscape student who is attending a university. If they are still in school I'm sure they could use some extra income. Also, if you know anyone who is associated with a Drafting school they may know of a student who needs work.
It shouldn't take them too long and any opportunity to get experience would be appreciated by most. Just think of all the people who worked in the food service industry who will probably be out of a job now. It's worth a try.
Plus, if you like their work you may want to hire help for the big tasks when it's hot, humid, & Hazy which is right around the corner. Ask Carlos if he knows any young adults interested in landscaping? I bet he does++++
