Wargames Foundry have lots of suitable figures. The Darkest Africa range and the newly re-released Egyptian Adventures are staples to the genre.
Crooked Dice get some of my money…Savage School Girls.
Northstar Miniatures also are rich with pulp figures. The IHMN figures work well for pulp and VSF.
West Wind also have lots of good pulp stuff.
Other ideas: Artizan, Copplestone Castings and Warrior Miniatures (England Invaded line).
Even with the postage costs, rationalizing Pulp Figures (Bob Murch sculpts) or Blue Moon from the US is very easy.
