I would put an advert on Freecycle, Freegle, Gumtree etc. for anybody that has unwanted tools. It is surprising how many people have things that they are very keen to give away.
You need to develop the skills of a forager - if it is going you will probably find a use for it - cardboard, pallets, bits of timber, sticks all sorts of containers
As well as the traditional garden tools you are going to need something to sit on, a flask or camping stove, stout boots, a tool kit - hammer, pliers etc.
Best wishes as it is a lot of fun and hard work
