I would concentrate on finding a commercial kitchen to work out of and getting more catering customers before you spend alot more money on a catering van. Have you considered renting a catering van maybe on certain days of the week or different times of the day. Around here they have mobile lunch trucks that take food to factories a lunch time I've always thought about selling them pulled pork sandwiches and having them re-sell to clients. I'm sure there is a way to sell your BBQ somewhere. Just keep trying.
