Hey, good luck with moving to the next step! A couple of suggestions about your Go Fund Me page, if you're open to them:
$50k is a big goal; you might go into a little more detail about exactly how the money will be spent. Is it purely for the land purchase, or for infrastructure,
earthworks, etc., or animal/plant stock, etc.? Maybe even how much money will you and your family contribute, if you're comfortable sharing that. I feel like people are more likely to donate if they know exactly what their money will help do, and if they feel like you are really invested and have been working toward the goal yourself (like if you've already saved a down payment, for instance). You might also consider a lower fundraising goal if you feel like that's at all possible, since I've noticed in the past that people are more likely to contribute to goals that seem fairly immediately achievable, where they feel like they're having a real impact moving things forward, versus when they feel like the goal is unsurmountable or too far distant and their small contribution won't matter much, so they don't donate. Pretty much the only people I've seen do well with large goals in the multiple tens of thousands of dollars are people who are "internet famous" or can mobilize a lot of attention and exposure (like Paul Wheaton, for instance, with his Kickstarters), but smaller campaigns seem to have more momentum as a general rule (this is purely based on my observations, not any kind of actual statistics or anything, so take it with a grain of salt).
You might also include some information about yields from your backyard where you've already been practicing permaculture (it looks great, by the way!). For instance, if your
yard is 1/4 acre or whatever, how many pounds of produce, how many dozens of eggs, etc. do you typically produce. And if you scaled it up to 3-5 acres, roughly how much you could expect to produce based on your track record, how many people in your community could that potentially
feed, what kind of profits you might be looking at, stuff like that. Any sort of business plan you have might also help, or sharing any design work you've done for the farm (I know that would be hard if you haven't got a specific piece of property to work with yet, but just some stuff about what kinds of crops, pasture systems, etc. you are thinking of, maybe).
I really hope this doesn't come across as intrusive or pushy, I just wanted to share a few things that I've seen help people get off the ground with fundraising campaigns in the past, although I'm no expert. I wish you all the success in the world with your fundraising and with your future farm!
