Licenses are only about the source-access and how contribution/
deviations are licensed.
You can charge any amount you want for your GPL'ed stuff - but the
source must be available for reasonable cost.
So, if one of your licensees redistributes a copy for free, that's
perfectly legal (for GPL).
Charging for PHP-stuff has always been very difficult.
Some use IONCUBE encoder etc.
I don't know if charging for support actually makes a good business-
You need a lot of contracts for that.
BSD-licenses carry a lot less burden - but of course you can't just
take a GPL'ed piece of code and re-distribute it with a BSD-licence.
If your free product is GPL'ed and your commercial product is a
derivative of that, it will also be licensed (well, need to be
licensed) as GPL - if you give it away to somebody. If you keep it
inhouse, nobody cares and nobody has a right to see the derivated
source, just because it exists).
You should really enlist the help of a law-professional in this field
- the licensing-minefield has gotten more and more difficult to
navigate in recent years.
This is especially relevant in cases where you want to have "dual-
licensed" stuff (as you mentioned).
