This question will tell you if the painter is informed about the lead issue or if he will downplay it to get the job. Lead paint is a reality that is best viewed from an informed perspective - and both the painter and the homeowner should be informed.
A quality painting company will tarp everything, arrange for furniture to be moved or covered in the area being painted.
If you're being steered toward a low cost product, find another painter. Ask for the top of the line of the brand of paint you want your painter to use for both the finish paint and the primer coat.
The construction slowdown has seen new home painters scrambling for work in older areas. Homes more than 30 years old have many layers of (possibly lead based) paint, aluminum storm windows to remove and replace, window putty, deeper soffits and very often more architectural detail. These homes require a slower, more methodical pace and different work processes. A paint crew that is used to only new homes will likely not be familiar with the attention and tedious prep work that an older home requires.
Typical is one coat of primer and two coats of finish paint
Interior painters usually charge per room. You can request that they break the pricing down into the cost of windows, doors, trim and walls
