No offense, but if you are taking someone's money for manufacturing vessels without knowing how to build a vessel, then you don't need to be doing it. Subcontract it out.
I would slightly pressurize the tanks with air and use a brush and soapy water on the outside to look for leaks. Not much pressure or you will damage the tank. In the states the best soap is Dawn or Joy dishwashing liquid.

Likewise I have found a little air pressure and soapy water to be a very effective way to find tank leaks. I didn't make a seal from the air line to the tank - I just wrapped a rag around the air line, jammed it in the tank's filler opening and added a little pressure.
