Hi Paul,
A suggestion...
Most good binoculars have a rubber sleeve on their out side to aid in you holding them & not slipping.
Please note that you only have to perform this on one side....say the right hand one.
Using a small blunt screwdriver & a small wooden toothpick or two, If you gently prize up that rubber sleeve at the top (eye piece end) & then gently move the screwdriver or toothpick along the rubber sleeve, you'll eventually see a couple of very small screws.
Now, with the binoculars held securely, look through both eyepieces at a reasonably distant object....say 100 metres or so.
Focus the binoculars & using the left side, line up your selected object & DO NOT move the binoculars.
Perform the "blink" test.
Close your right eye, observe where the object is, the do the left eye & note the object's location.
If it changes position, then you need to collimate the binoculars.
Best if you can place a reference mark on each small screw before moving either one.
You do this by very, very carefully & slowly, turning one of those small screws at a time BUT only on the right hand one.
You must do the "blink" test after each tiny adjustment.
If the "view" gets worse....going the wrong way, then turn that screw back a bit more past the original reference mark.
Takes a while but it can be done.
Take you time & make sure that the binoculars are solidly held.
I've done this quite a few times.

Another suggestion....
Try any optical/opticians shop, as they may have a contact that they use.
