Conundrum

OK, here's the situation:

I was unable to sleep one evening and randomly submitted my resume to another company that was looking for an admin assistant position, and requested a salary requirement in the cover letter. I threw a number down, considerably higher than my current base salary and still higher than what I make with my quarterly and annual bonuses, thinking that I would never hear back.

Well, a week later I received a call from their Director of Operations who was very impressed with my resume and wanted to speak with me about the position. I managed to return his after a few misses, as it was difficult to find a quiet space to call and I had worked through my lunches and late. Well, he talked about the company and about the job and said that they were prepared to offer me what I was asking because I had experience in the area and I knew what "redlining" was and how to do it.

Anyway, I mentioned a couple of my concerns and the hours that I wanted to work, which are slightly different from their hours, because of daycare schedules. He said he would talk to the partners that I would be supporting and he didn't think it would be a problem. This job would basically entail supporting four Partners and the Director I spoke with with the basic, plus reviewing leases and proposals, etc.

My concerns are do I want to take a step backwards in title for more money. The office I would be working in is larger, so down the line there may be something better. But that's not guaranteed. The company I work with is growing, as well, but only has 8 (soon to be 9-10) people. I have my choice to support my current boss and continue to run the office or go more towards the marketing side and support our leasing rep and soon-to-be project manager. This would mean that I would get to do all the fun stuff that I like about my job (doing the creative bit). I think, if I had my druthers, I would work with the leasing rep on the marketing and run the office and let the new admin work support Joe and the project manager.

I don't know. I have my list of questions for the lunch meeting tomorrow, but need someone to start soon, and this is a bad time to leave my office. Our leasing rep's wife will be having the triplets within the next few weeks, and my boss will be out traveling for several upcoming meetings. Our associate property manager is on maternity leave, so we have a temp filling in with some of the support work and phones, while our customer service coordinator does the assoc. pm's job. The temp is leaving at the end of next week because she landed a permanent job elsewhere (child-welfare protection as a case worker).

I would hate to seem like I am taking advantage of the situation should my boss decide to give me a raise to keep me, but I also don't want to leave the team in a lurch, since I like them for the most part. Plus, my job is fairly interesting. Yikes. Then again, I have not officially been offered the job, even though the Director did seem quite interested in hiring me.

And we do need the extra money to pay off all of our debt (the horrors of having to use the cc to make it through the month) and start saving for a house and college funds for the kids.

So, what are your thoughts?

UPDATE:
I was offered the job officially today at a little lower than I was expecting, but not too much. DH has been hashing over the pros and cons and I still have not come to a conclusion. Now to talk to the boss tomorrow. Ack.
