What to charge..? (horse sitting...)

So, long story short, I kinda went into business with one of my hunting buddies' wives - she was involved in a pet sitting business that did pretty well when they lived in South Carolina, and I could use some extra cash, so I said I'd work with her up here. We have a price set up for dogs/cats - house visits, basically.

Then this guy calls the other day, he's leaving for a month or so, and needs someone to look after 8 Arabs. My partner is not comfortable with/has no interest in/really does not like horses. I grew up riding and am relatively comfortable with them, Arabs (call me crazy...) being my favorite breed.

I guess they're all old-ish (in their 20s or so?) and from the sounds of it they just need hay and water refilled. It's probably a 20 minute drive out to his place for me. SO, before I call him back and agree to go meet the buggars, WHAT DO I CHARGE PER DAY or PER VISIT FOR THIS?!

I am ALWAYS undervaluing my services - and it bothers me, but I'm really bad at asking people for money, too

I don't know on the charging front. But I have farm sat for fiends before (sheep horses dogs and cats sort of thing)

Things to think about with livestock.. What happens if one dies. I had this happen. Sheep die easily, and I was to put in the back of the 6 wheeler and dump it out the back for the coyotes. The worst was when I showed up and one of the older horses were dead! He was in his mid 20's and had a bleed into his lungs. It was fast and nothing could have been done no matter who was home. BUT a dead horse is a little different than a dead dog or sheep.

Make sure they have a plan for you to follow if something untoward happens.

That was one of my foremost concerns, and definitely something I'll be asking him about... the idea of watching 8 "elderly" horses in a PA winter made me think of that.

(Sheep are born looking for a place to die. lol)
