Pediatric Case Manager?

help! i have worked for a pediatric home health company for a little over a year now, earned my rn and am considering taking a promotion with the company to do case management. never done anything like this, so i have no idea what questions to ask, what kind of salary to request, and whether or not this would be in mine and the company's best interest! i live in central missouri, the company is small, takes kids with home health needs. i work part time, and would continue that. what little i know about the position is that it would include monthly visits to the clients, and possible iv visits, blood draws, etc. i would be able to set my own schedule, as i also work full time at the local hospital. any advice? love the company, excited for the possibility of a new challenge, but want it to be right for everyone...also don't want to ask for too little money, or too much....help! thanks! julie
