Lead Inspection Equipment Cost?

How much does the equipment cost that a lead based paint inspector would typically use on an inspection? I’ve read that an inspection includes using a hand-held detector which may cost $15,000 in addition to gathering paint chip samples for outside laboratory analysis.

I have been reading about requirements for becoming certified in lead inspection. In my State it looks like I need a 3 day lead inspection course ($600) passing required exam and paying registration fees. So, for $1,000 I can get licensed but then I need to consider the cost of insurance and detection equipment.
