Yep, you are right Lynda (2catmom). I shot off an email to Enviroscience in Ohio and got a reply very quickly. The email was quit long so I will only post the part about cost.
From Nancy Cushing who is a Research Biologist from Enviroscience:
[With most lakes we incorporate pre- and post- application monitoring surveys in our projects. Under this program we perform initial baseline surveys at the time of stocking and then survey again at the end of both the first and second seasons to make sure the weevils are reproducing and spreading around the lake as expected. The surveys allow us to chart our progress and provide the association with detailed progress reports. The survey component also includes fees associated with stocking the weevils and generally costs between $4,000 and $5,000 for a single stocking program and for most lakes within 400 miles of our office. In addition, we add the cost of the weevils which are sold in units of 1,000 at $1,200 per unit. We do not install less than 2,000 to 3,000 in any one area of the lake. Most of our clients will place three or four thousand in several locations around the lake. In most cases, it probably does not make sense to spend less on the weevils than you do on the survey, so our smallest lake projects are generally at least $10,000 and have gone up to $150,000.]
As you can see these little buggers cost about $1.20 each. I have a privately owned 15 acre lake and in the summer time the milfoil is terrible making fishing and boating difficult.
Here are some photos of my lake and you can see the milfoil bloom.

Thank you for all input to this thread. Thanks.
