Bobbi Brown is known for her natural makeup looks. Clinique tends to be more natural too. Most brands do makeovers for free if you're just trying on makeup for fun or to see what works for you. But if you need a makeover for a special event, then they'd charge. They will all try to sell you product, even if you pay them.
Your best bet might be to go to Sephora and ask a consultant there to give you a makeover. There, they aren't beholden to any one line. They're knowledgeble and pretty good about "hearing" their customers. They also tend to be less pushy IMO than many of the single-brand sales people.
