Well, after much appreciated input from this supportive community, I accepted the position at a smaller rural school. Money wasn't a factor initially, but it did end up playing into my decision.
So here are the details so far. There are two campuses (k-4 & 5-8). I will be setting up an office on each campus (NO SINKS OR TOILETS in the office, but will be strongly pushing for sinks at least).
If you can take a minute to think of everything I will need to have on hand, even documentation systems (I'm starting from zero), how you manage records best, how you store meds in a small offices, and any other tips or ideas you can give. If you post and think of something later, please come back to post more. I truly appreciate any support, help, ideas, and tips from the awesome school nurses here.
I did find a school nurse conference near my area that I do plan to attend, and hoping to meet some resources/contacts there as well. I tend to be an over-doer, but I want to make sure it's as perfect as it can be. I need to show the school that the position is worth their investment, so they'll continue to keep it in place.
Oh, about how long do you think it would take to set up from zero to go? Is 10 days enough? That's what the superintendent mentioned, but we are to talk more later. I'm thinking at least a month, but I'm also thinking about preparing records, policies, etc.
I'm working full time now, but may leave my job earlier than intended in order to best prepare for this.
