Two Helpers for Hire

I have two happy helpers that are available for hire. They are quite accomplished at planting in the garden. Give either one a seed and they know just what to do with it. One can poke the holes while the other one can cover the holes, and stamp all over them.
Of course there is the need to settle on the terms of payment. Each happy helper, I have two, requires a $5 per hour wage. Plus naps and snacks. Travel expenses are calculated in 'time and a half' rate. These happy helpers are to be hired out as a pair and I come with them wherever they go. My wage is also $5 per hour with 'time and a half' for travel expenses.
As you have probably guessed by now, these kids are quite expensive. But they are PRICELESS to me!
