While you did get a nose bleed, your gonna be fine.
I like you going to at least talk to the guy.
As others before me, the first time I was faced with a tire change I almost had a stroke
I made up my mind I will do it myself. My dealer will not even mount a tire not bought from him. Liability and all that stuff
I bought a HF and used it the first time with minimal damage to my rim by using rubber inner tube on the clamps.
The next one I just lug the bottom part of the HF, lay the rim on a moving pad doubled over, and break the beads. After that, it is spoons and rim protectors, off and on.
I also have had the pleasure of using a Mark Parnes balancer, and that will do it. I have no room or money for a good wheel machine and balancer.
With my method, I get it done, clean and inspect my beads and rims, and save a bunch of money.
I would say If I can, anyone can. All you got to do is keep it in the drop area of the rim.
I am using radials and I have heard it said that a Bias Ply tire is a bit tougher.
