Large contrs for Hyde tanning (HD4)

I have been a bricklayer from leaving school, then September 2020 I had an aneurism (never heard of 1). On waking up I have had to learn to walk and other things we won't go into. Anyway I can no longer work as a bricklayer, so I am trying to get my own tannery up and running from scratch lol,so any help would be appreciated
