Just keep in mind that there is no record of a parrots killing anyone. A bite may bring blood and hurt, but it will quit bleeding and quit hurting. It just isn't that big of a deal.
Don't miss out on everything wonderful with your bird just because of a few foolish fears.
Taking your advice, and manning up
ive been hand feeding him veg in his cage, tonight he kept trying to get to my hand and missing the veg I kept moving away.
So tonight I thought, let’s see what’s going to happen, offered my hand and basically closed my eyes and prayed to the birdy gods.
He put his beak over my hand and just moved around very, very gently nibbling, my heart was racing, I honestly can’t believe how scared I am of that beak, (I know I won’t die , ,but it’s hard to anyway I got a little nervous and tried to move away, I touched him under the beak/chin and he freaked a little, I tried to touch his head and same, so I decided no more.
he reached over with his foot and gently held my finger/hand I left it for a second or two and tried to put his foot back on a perch (remembering someone said, always finish on a good note) but he decided to grip
he gripped quite firmly, not hurting but enough I couldn’t pull away, I then realised I had no choice and regardless of what happens next I can’t move or pull away as I’d hurt him or pull him off his perch, so just gritted my teeth and waited for the “chomp”
he nibbled my finger and I tried to get him to release but the more I moved the more he gripped, so I had to wait it out.
he nibbled and held for a minute or two then let go, my other half was laughing at me as all I was saying was “Bert be good” “bert be nice” .
I felt completely out of my depth for the first few months. Hoping you take it easy at work - sounds like a dangerous business you are in.... but not as dangerous as living with a parrot! 
way to go
