The equipment has been made in UK sizes if you don't want Langstroth. The new machines for drying cappings are brilliant. Unlike a cappings spinner (shown in one of the videos) they work continuously so don't need to be stopped to be emptied - and they sit under the uncapper so take up little room.
A few tens of thousand of Euros for the full works, although the manual uncappers are around £3K each, a bit more for a motorised version. As PH says, the deeper the pocket the more frames in your extractor so to speak. Bee farmers in some other European countries get significant subsidies for this sort of equipment. Not so here sadly.
As usual with beekeeping everyone will have a different view on where things should be placed so the only help I can give is to think about it long and hard do a few sketches and then do it to suit your needs.
Visit as many big set ups as you can as if you are seriously spending several tens of thousands or even 100's of thousands getting it wrong is not just not funny it's potentially disastrous.
When it comes to bottling you have to work out how many pounds a minute you can put in jars against how many days it takes to warm drums and mix and or cream to have enough in hand to keep your staff working. A not so minor point...A big rig up needs one to feed on jars, one to pack at the end and possibly one to put on lids if you dinna stretch to a put on lids machine. A labelling machine is pretty much essential.
Extraction wise it is not so important to have a massive set up as you have all winter to do the business. A warming room will double for prepping supers for extraction as well as warming up drums of product. And 220 lbs takes a bit of warming.
