Multiple flat rates for shipping

[jmouse]

Hi

I would like to set up the cart to allow the user to select the type of shipping they want at checkout time and add the appropriate rate per item.
I've looked through all the shipping options and cannot see how this is done. Can anyone assist?

Options would be
1. UK Next day delivery - per item
2. Standard UK first class delivery - per item
3. Europe Airmail Small Packets - per item
4. Worldwide Airmail Small Packets -per item
5. Standard UK Postal Rates (by weight) for small items such as thread, glue etc.

Possibly an acceptable option would be to have a flat rate per item, plus an addtional customer selected charge for anything 'special' in the way of delivery.

Thanks
