Well years ago when I started my to live self sufficient (SS) I decided to start out with a fund of 1500.00 and see where that could get me and I would figure the rest out. Buying the 1954 harvester super C and 48 inch box tiller put a huge hit in that amount, and after purchase of more jars for canning, I have since stayed below the 1K mark but with sales of goods from canning, bartering and trading have kept that going.
The funds are to improve my garden and level of planting and producing food to consume or sale/barter with. The eggs are still being sold to friends and that money goes back into their food fund as well as my SS fund. I have raised my prices to just below what the super market are selling their organic eggs locally here. Their selling theirs for 3.69 a carton, so I am selling mine for 3.00 a carton.
Each improvement I make to my property/garden comes from my SS fund, and its doing okay, not as much as I expected. I didn't tap any trees as I was going too, I need to design a cooker to cook the sap down.
