Floor pan replacement

[Alice]

So we finally found some rust worth getting worried about in the 77 Mk1. It's bad enough that we can poke holes through the floor haha.
My quest now is to find a reasonably priced front left/passenger side full floor pan to replace the rusted one.
I've tried ebay and VW heritage but since they're shipping from the UK the shipping cost is almost as much as the panel costs.
Can anyone recommend somewhere to try (either overseas or in Aus) that will be reasonably priced?

Also any advice on how to get the carpet up without taking out the entire dash (if that's even possible) would be appreciated.

Thanks!
