Me and my cousin have just recently launched a joint-venture, selling energy contracts for a commission. We are acting as energy consultants and brokers, the latter of which entails some sales work. I am targeting large government institutions, and I have already booked a few appointments with key decision makers for early December. Going together with my cousin as a team would facilitate the consulting process, as he could review the energy invoices and crunch numbers while I speak with the individual (and vice versa). Is it proper business etiquette if two individuals, acting as associates, conduct a meeting with a key institutional decision maker? Or is a sales/consulting rendezvous a one man show? Thanks!
