Where can I find someone who can take an idea for a commercial to a big corp.?

Question

(And get a good price for it?) (or an idea for a product name or a business name or a business "quote"/"tagline"?)

Answer 1

Most companies don't come up with their own commercials.

Big companies hire ad agencies to develop their commercials for them.

So you could go to an ad agency.

There are also firms that specialize in product names (especially drug names) and merger names.

But since, these firms are way better at this than you (they do this stuff daily), they probably won't listen.
