Forklift Operator Jobs?

I've been driving a forklift for the last 2 summers in a seasonal job moving pallets of mulch and dirt around and I really enjoy using power lifting equipment and heavy machinery but the biggest thing I've used is the fork. I'm interested in doing this for a living full time but I've heard that alot of warehouses are only concerned with getting things done fast and skimp on the safety part of it. Does anyone know of a good company to work for in this regard? How much they pay and if any pre certifications are needed?
