They've installed bee hives to boost the number of pollinators on their land, rear their own livestock, grow their own food, and even manage their land to benefit bio diversity - using goats and geese to clear weeds over chemicals.
It's no surprise, then, that Josh counts FTSE 100 companies among his clients.
"We help them with coaching sessions to find a solution to problems they face, point them in new directions and even teach the necessary skills to young people who want start their own businesses," Josh says.
So what lies behind Josh's entrepreneurial spirit?
"When I left college a few years ago, my friends either went to university, travelling or got a job," he explains. "It hadn't occurred to me that running my own business was an option.
"I started writing a blog about creative projects that I was doing in my spare time, sharing my projects about my creative, science and technology ventures, such as sending a weather balloon to space and capturing it on camera or filming the bottom of the ocean."
While writing, Josh says, he met social entrepreneur Trudy Thompson, who encouraged him to turn his hobby into a business, and offered him free coaching sessions.
"This help was so valuable it helped guide me into being a real entrepreneur and I felt compelled to share this experience with other young people who don't know which path to take."
Trudy and Josh became business partners and, as they say, the rest is history.
