Hiring for the Team

I've been with my org. almost a yr and I have an opening on my team due to a resignation. When I started w/ the co. I was told on my fist day that the account clerk wasn't happy in the position and was looking for a new job. I met w/ her to better understand why she wasn't happy and to see what I could do to make things better. I soon discovered that my co. was very dysfunctional and the culture here is hostile. I've spoken w my boss about ways to improve the functionality of the dept and some of the hostility I've experienced, and how we can improve things, but he's not interested in changing anything (and that's me putting it nicely because his response was filled w profanity and yelling). I've also spoken w/ HR about the position because it is low paying and has limited responsibilities so I wanted to restructure the position to give it more duties and to increase the pay. I also spoke w/ HR about the hostile culture. The response from HR was to increase the duties, but the pay would remain the same. They acknowledge the hostile environment and have gotten complaints from others, but no further resolution. So I have a bit of a dilemma because I need to fill the vacancy, but I don't want someone to be blind sided coming into this org. because it is very hostile here. I have a decent rapport w my team, but may of them are burned out because they've been w/ the org for yrs and when it comes to dealing w/ other depts., ppl are down right rude and belittling. I've also learned that there's been high turn over in my position (which wasn't the answer I was given in the interview when I asked about the vacancy), high turn over in the accountant position, and high turn over in the account clerk position. In the past 5 yrs., the org. has had 4 ppl in the account clerk position. So my concern is, how do I hire a good candidate for a low paying position, and how can I be honest in the interview about the corp culture because it is a factor that someone should know upfront.
