If doing your own fencing and doing frameless glass I strongly advise against using bolt down spigots - glass panels are heavy and having them fall over could be a disaster.
I always prefer to core drill posts/spigots wherever possible (even semi frameless or tubular) but you need extra thickness along the fence line whether limestone or concrete under paving.
I'm sorry to hear you are feeling like this.
It really puzzles me as we have found all of your list in and around Perth so maybe as another poster said, perhaps it's the suburb/area is wrong....where are you now ?
Perth is a very large spread out metro area so is naturally very varied from one part to another.
Letton Percival or Insure-Your-Move are the only 2 players in the non shippers market.
IYM charged us 600 pounds for 35000 pounds worth of goods and a small claim was easily dealt with.
Electrician will give you greater state choice (assuming you are looking to be state sponsored) as data cabler is only on the SA list currently.
My assessment for telecoms tech was through TRA back in early 2011 and took 8 weeks.
Not sure what visa you are applying for but data cabler isn't on the skills list so you are better off on the sparky route as long as you've been doing this work recently too.
By the way nice to meet a sparky that knows how to data cable - a lot do it here but the quality is rather shocking in a lot of cases.
The crazy thing is I (as a telecoms tech) had to pay for training to become a registered cabler here but sparkies can do Comms cabling under their licence with no training ??
But a century old house in the UK would have had a lot of upkeep/modernising over the years just as our new Aussie houses will, I will be surprised if they reach the age of maybe 60years and just collapse !?
