Note that on all platforms, the library "httrack-plugin" is always checked for
loading (httrack-plugin.dll or libhttrack-plugin.so) ; you could have a
library copied on the winhttrack/webhttrack directory, that could trigger the
desired actions without needing any specific option to fill.

Humm, I'm not sure this is the good solution -- you need some clear designing
before renting a coder ; and unless you find a good designer and coder, it
will not help much.

Except for research/archiving projects, I really don't know anyone.
