Get testimonials from past and current clients. Don't have to be long and drawn out but word of mouth is the best advertising, so put some in your brochure.
In the layout portion, make it flow and use color. Yes it is expensive to go full color, but color sells and makes you look more professional. Gloss paper stock is a nice touch as well. Doesn't need to be to heavy, but shouldn't be to light. Start looking at what other brochures are printed on and how they look and see what you like.
I am glad the catering side has remained. I was bummed when I read that you were closing and wasn't sure what direction you were going to take.
