Reply to Lighting Question

Hey DJTT!
I don't know if this is in the right community or not but I didn't really see anything on here for lighting and seeing as how this is my favorite community , I thought I'd start here.

Recently I got hired to do the first big dance my fraternity is putting on on our college campus. I have two qsc k 12 and a kw 181 so I'm not worried about sound in this venue, but it is significantly bigger then what I'm used to as far as lighting goes.

I will be on a stage with a dance floor (30 ft by 30 ft approximately) and the entire building (50 feet by 50 feet approximately) will be dark. My fraternity wants fog as well as some other lighting effects.

My questions are:
What kind of advanced lighting set up should I be working with? I currently only have a chauvet equivalent to the adj vertigo

and a chauvet mini

Should I add more wash and effects or will the chauvet mini be enough for wash and then add effects? I'm willing to spend up to five or six hundred for the additions to my set up

Also, any recommendations on a decent fog machine? Will I need 2?

I know it's just a lot of general questions but any help would greatly be appreciated!
