So, in case anyone here is interested, I heard back from the kind folks at Dege & Skinner and here is some of the information I received:
"Our 2 piece Bespoke suits start at around £3400.00. For a Super 130s to Super 150s, the price will increase to around £3800.00 - £4000.00. These are Sterling export prices as you do not have to pay our VAT (20% tax)"
The above comes from Shop Manager Matthew A. Cowley. Now, to check the bank account and decide on fabric and style...
If I do end up commissioning something I will be glad to document it here on SF if anyone would be interested.
