Buying land, have a vague idea of what I want, who do I talk to?

I am buying a significant amount of land (between 20ac and 80ac, to give you an idea) and I want to turn it into a generational homestead. I hope this is the right place to ask: who do I talk to, and how do I find one, to figure out how to utilize this land?

Some features of this land are:

• It is gently rolling grassy hills with a steep hill on one side that is forested.
• There is a seasonal stream on a border and perrineal stream running through the land.
• Dead center of the property is a low spot that is in the 100yr flooding area but currently supports local vegetation, mostly shrubs, no tall trees.
• Two boundaries are roads.

What I’d like to do is:

• Build a small, temporary home as soon as possible and plan to build a permanent home later, with considerations of building another 3 homes over decades for family.
• Either fill in the low area or use it for permaculture trees such as persimmons which are endangered now in the US but apparently thrive in shrubby areas like that.
• Plant a privacy tree line on both sides with roads.
• Erect insect hotels to promote pollinators, perhaps also erecting vertical solar panels on top to make use of the space?
• Put something up for birds. I’m aware there’s a voracious tick eating bird that only nests in holes in trees that are near water and face a certain direction, and I believe this species is also endangered.
• Plant fruiting and nutting trees.

Basically I need someone already very familiar with homesteading who already knows all the cool stuff I want to learn and can help me get what I want out of the land so even if the bombs drop I’m making acorn bread. I do work so what I set up needs to be managed by someone who is not in ag working for himself.

Thank you
