The cheapest place I know is Sea Test. You need to have your initial DOT 5 panel drug test done first. Then when you get the results, you can fill out an application and send in your initial test. You'll want to call or email Dennis first, before you send anything. He's a captain and his summer residence is different than his winter residence, so he'll tell you where he wants the paperwork sent. I believe his first year is $60 and then $40/yr after that. The other place I know without looking it up is the Lake Erie Charter Boat Association. I haven't dealt with them, but I know others on here are. They may chime in.
