custom cut Showgard mounts wanted

Would anyone be willing to sell me some black Showgard stamp mounts
cut to some custom sizes?

I have a few stamps I'd like to display. From looking around online,
the Showgard mounts look like they would work well. But I'm not a
stamp collector so I'd rather not buy a guillotine cutter and a lot
of strips and never use them again. If someone wouldn't mind cutting
me the sizes I need, I'd be willing to pay you whatever is reasonable
for the mounts, your time, and the shipping.

Or I have about a dozen leftover mint stamps from China (PRC), if
you want those.

Here are the sizes I need (width x height):

2 25mm x 30mm mounts
2 30mm x 25mm mounts
2 40mm x 30mm mounts
8 50mm x 30mm mounts

If you can help me out, please email me.

Thanks,
+++
