The land would be the easy part. Hiring a PI, a team of subject matter experts on botany, metallurgy, and genetics, a few skilled lab technicians, a couple programmers or statisticians, an environmental compliance expert, and whoever else I forgot, probably costs more than $1M/yr and ideally there would be more than a single team. I have no idea what reagents and bespoke GMO plants cost, but it can't be cheap.
