I know this will sound a little odd, but I usually let guys determine their rate. I ask them how much they want and what conditions. When they tell me, I pay them that, and a bit more for a TIP. It usually works out. If it's not, I can tell them it's not working, or not have them working with me. I've found that most guys know their worth, and some rare guys who don't know it also are not the type of person I want on rope. Also, $10 is the new $1. $100 is the new $10. We all need to be pricing stuff for the 2019 economy - wages, estimates, etc. The whole reason why employees are hard to rustle up is that it's just not worth the pay. That's part of why I ask potential employees to name their rate - they are more invested at that point. They have agency at the very start.
@Gorman also want to hold you accountable for that "with tattoos everywhere but", which should be "with tattoos everywhere and".

Tattoos and ability to work on trees are two separate things, right?
