That way, it's a more consistent income and no one hears "free" because that is the word they will focus on and I see nothing but trouble when that word comes into play.

You can accrue PTO however you want. I "reset" my time off every September 1.
I agree, 50% iOS better. I also reset things in september first. I don't have writing how many days I will take off per year but I also choose to to not charge but my rate reflects me not charging. (per suggested by Tom Copeland)
My question is if family a starts in April and you vacation in may and start family b in June then take another vacation in August, are you going to charge family b for your second week?
