You can charge any price you'd like for GPL'd software. To every
customer, you must provide the source code, or an offer to
provide the source code for the cost of shipping it to them --
which, in the era of semi-ubiquitous Internet, is a few pennies.

You can sell non-GPL software and then GPL it later. You can
sell software under one license and give it away under the GPL
at the same time, as long as you are the sole copyright owner or
have all the other contributors agree to the arrangement.

You can give away or sell GPL software and charge for support,
or charge for custom feature development, but you can't forbid
anyone else from doing the same with their copy of the source.
