Pitching for business is the hardest thing!
Technically you can use the simplest set up of 1 light with attached brolly and a Lastolite reflector on a stand. For group pictures a bigger set up could be required although I once photographed 100 people on a staircase with the gear described below.
A Prolinca kit comprising 1 x 500 & 1 x 250 flashheads, 2 stands, 1 white + 1 silver umbrella. I also use a large round Lastolite white/gold reflector plus Lastolite stand adaptor along with a lighting stand to attach it. Sometimes I'll switch to a larger white Elinchrom brolly depending on if a softer light or bigger spread is needed. It virtually all fits in 2 neat custom kit bags which are kept in a bedroom cupboard. The Lastolite folds flat into its own bag.
Essentially, Prolinca is Elinchrom but a budget version. The limitation is that the lights are adjustable for full power or half. That's why I chose to include a 250 light rather than 2 x 500's. Interiors (depending on dimensions etc.) photograph fine with this outfit too and pics are perfect.
The other essential is a flashmeter. Mine's a Gossen F2 but I've used several including the cheapest imaginable and got the same results. Getting on with people is another essential I think, but I know photographers with almost no communication skills who get more work than I could ever aspire too.
Portraiture tips and hints requires a book and there's plenty around. An Amazon search will reveal them. Personally I wouldn't get too engrossed - just go out and do it.
