If you have a conscience, before taking the client's money you'll take
the hint from Loren and explain what he'll end up with. If he's still
interested, then try to locate the documentation you'll need and take
his money.

If people didn't like cheeze, there wouldn't be so many cheezy mic
preamps. But if you'll be charging like a professional, he can probably
buy cheeze off the shelf cheaper, and can return it for a refund if
it's too cheezy or not cheezy enough. You probably won't offer him a
refund on your labor if he doesn't like what he ends up with.

But like you say, it's the customer's request, and the customer is
always right.
