LornaDoon

I am a cnm with 7 yrs experience. I have been offered a position in a physicians office as a contract employee "because I will be part time." I am not entirely sure what all of the implications are from that. I assume this means no benefits, no pto, etc. I plan on clarifying what exactly this means to him but I wondered if anybody had any experience with this or advice to share. He wants me to tell him how much vacation I want so it can be written I to the contract...totally up to me how much. What else do I need to make sure s included in the contract to protect myself? The payrate he is offering is ok but not great considering no benefits but will go up in 6 mos or so when I no longer need to be proctored (ice been out of practice a few years.. he wants to follow me for awhile)....any preference autumn's or advice there? I completely suck at negotiations.
