Woocommerce shipping costs plugin

Hi there!

We have an online-music equipment store that we are about to launch, there are just a few more issues that needs fixing.

One of the issues are that we just can’t find a plugin that meets all the requirements regarding our shopping cost.

We need a plugin that could do the following:

? Calculates rates according couriers formulas and surcharges (volumetric weight and distance)
? Compares calculated rates and chooses cheaper rate for client
? Adds the rate to checkout and says which courier is being used (i.e. R99 – DHL )
? Adds the courier charge to the checkout fee
? Notifies the shop admin on the order as to which courier service to use
? ability to add parameters per courier(i.e. 0 – 10kg R99, 11 – 30kg R149 etc.)

We did try the table shipping plugin, BUT its not exactly what we need. Can anybody advice as to what plugin could do the above or any kind of solution?

We would really appreciate the help!
