I would like to make an extra shipping module that does the following:

Only show up if:
  • all products in the order have weight added
  • the total weight of the order < 340 g
  • the total value of the order < $50


The main thing is to only show this shipping alternative when the above criteria are met.

If possible, I would like to have the module show one of two prices:

$3: If total order weight =< 90 g and total order height =< 2 cm
$5: If total order weight > 90 g or total order height >2 cm

But a flat rate of $5 is also OK.

No zones needed.

Does anyone know of a simple module than can easily be modified in this way?
They ones I have found seem to be too complex in the wrong places, or not give the possibility to hide the shipping alternative when necessary.
