Bloomer, you're only planning a summer stay - I have the chooks and enough Highland ponies to be trained to do most crofting and transportation work, haul peats, sheep checking etc. My shopping list is therefore quite a lot shorter:
Island £500k - offset by sale of 10 acre Fife smallholding with mature orchard but need the lottery for securing purchase prior to knowing what the sale will make at closing, plus the inevitable extra, plus the rest of my list..
Polytunnel a must, preferably 2
Transport out for a dozen or so Highland ponies, 20+ chooks and key equipment/personal possessions
Log cabin with solar panels
Generator for emergencies
Animal housing, a large solid barn for everything including equipment
Probably need a milk cow, perhaps with a heifer calf and in calf, a Shetland probably most likely to thrive - could milk a sheep but I've a sore back so it'd have to stand on a table!
Reckon I could arrange a weekly, maybe monthly boat visit from Benbecula without having to buy a boat, but if I could get a wee one that would do me fine
I can manage with a camping stove but a raeburn would be my luxury item if it's a good lottery winning..
