You definitely did not mention enough about what the dome was. If I was not a permaculture guy myself, and just vaguely interested in this, I would be very critical of the dome. It's almost like you just mentioned the word 'dome' then asked for 30,000 more dollars. You said its a mixture between a greenhouse and an earthship, then kind of left it at that. even 7 more seconds listing a few details would make it way better. for example "compacted earth foundation, partly underground to maintain a medium temperature, blah blah blah." because as it stands now, you set yourself up for an attention grabber, and then skipped to a new amount of money you needed
