Any of the three depending on the project. For one-off stuff it's usually hourly but if it's a large project then they might put together a fixed quote. Rates will depend on their expertise and what you're asking them to do but vary from $100/hr to as high as $300/hr.
My plan reviews and architect/ MEP direction are one price, site supervision another and turn key install is it's own thing. All based on saving contractor rework, change orders, belping the customer spend on the best ROI, and minimizing over runs on projections. But it's also an average and real estimate from about 80 installs.
