That's your first mistake. It may be unethical and frowned upon
by the community-at-large, but nearly all open source licenses
(including GPL) allow for the code to be sold. From GPLv3:
"You may charge any price or no price for each copy that you
convey, and you may offer support or warranty protection for a fee."

That is correct by all means, because you're charging a fee for a
service, not a fee for someone else's work or derivatives.

GPL doesn't explicitly require that. That would be licensing by
the individual project.

Quite honestly, if your client is willing to pay for removal of
the links, you should work with the original author(s) to determine
the value of the script(s) you'll be using and request a commercial
license. In so doing, you're not only abiding by all of the written
and unwritten laws of the community, but also supporting a project
financially --- which is ALWAYS welcome.
