What are some good ideas for home office space usage?

I am buying a new home with tons of office space. I have alot of experience in administration, office management type positions. I am wondering if I might approach different businesses locally and from afar, to see if anyone would like to hire me and I can use my space for a multitude of functions. Some ideas might be in sales or consulting...or even employment agency...my space could be the office or reception area and I can even host dinners, banquets or even socials. My space is an old photography studio and it is like a mini gym, tastefully docorated...it has a reception area, an office attached and about 2000 square feet. Any ideas on what I can do with this space would be greatly appreciated. I am going to run a daycare out of there for a year or two, until my boys are in school, but I want to begin planning on what to do with it then. Ideas please! Thanks!
