Thanks a lot for the heads up - I've emailed Dave.
Yes I did contact Omicron back in 2021 and got a outline quotation but after a few chases re availability to start work I never heard back. To be fair I got the impression they were mega busy and I wasn't 100% motivated at the time to push it hard enough, so left it. I may get back in contact with them also given they are very capable and aren't far away from me.
