Right I'm going to wade in and say get a trainer!! Preferably yesterday. It is very very clear that you havent a clue when it comes to training a horse.
Knock the oats on the head (rocket fuel) and look at a general cool mix or cubes if he needs anything.
I am in a very similar situation to you. I to have a coloured horse who has just been broken, is incredibly sensitive, has had bad experiances in his past and has major trust issues, he is hyper and has the attention span of a gnat, I swear if he were human he would have ADHD. It took 8 monts to get a saddle on him, it took nearly a year to be able to get on him without him trying to kill you.
The difference between you and me is that I have experiance in dealing with training issues and I have enough experiance to know when I was in over my head and needed help. I got help (from a real trainer who came to work with me and him together) and I now have a beautiful little ridden horse.
He happily goes exactly where I tell him out on a hack, even if that is belly deep in water. He rides out in the heaviest of traffic, birds can attempt to fly up his nose or into his bum, but because I tell him to keep walking he keeps walking.
It has now been 8 weeks since my lad was sat on for the first time ever. I have him working in self carriage in walk and am getting there in trot. We have incredible hacks out together and he trusts his rider now. We are working on physical strength and fitness now.
Yes he can feel absolutly explosive under me, but I just have to sit quietly and get his concentration back on me, teach him something new and get him away from thinking about exploding.
I've had a horse try to lie down under me (we went paddling in a lake and he started buckling at the knees) a very swift boot to the ribs stopped him.
The main problem is you came on here asking for advice and when several very experianced people are all giving you the same advice you choose to blatently ignore them.
There is no shame in having a trainer to help, even olympic riders still have trainers. Infact I know a lady who breaks troublesome youngsters for international eventers.
