That's a very good decision on your part. Far too much risk for your first "catering" gig. I remember my first paid gig was for a friend of mine hosting a poker party for 20 and I was really nervous. That was almost four years ago. Over time, I've accumulated more equipment and experience so that groups of 100 or more are no big thing. Take it slow and find a mentor to help you avoid the usual rookie mistakes. You'll get to the point where you can cook the big projects in due time. Best of luck with your party!
