I am trying to begin developing two custom shipping methods for Magento but have become stuck.
I would like to create one for "Standard" delivery which will be calculated using Weight Vs Distance.
The second module will be "Priority processing" which will also be calculated using weight Vs distance but needs to have an additional charge.
I quess my question is are there any tutorials or skeleton modules that I can use for this? i have created custom methods in the past but I have never been able to add the ability to add an additional fee or calculate weight and distance as most are based on the "Flat fee" type of method.
I would be grateful for any tips and I will gladly share the module(s) once I get them working.
