I bet this is just a scam of some sort to get gullible Christian investors. Rebuilding the temple would involve overcoming difficulties not even imagined by FReepers.
I know nothing about this particular company or effort, but rest assured the temple will be rebuilt.
The biggest obstacle to building the temple is the Dome of the Rock. But the temple can be rebuilt beside the DOTR if the outer courtyard area is not rebuilt.
Revelation 11:1-2
Then I was given a measuring rod like a staff, and I was told, "Rise and measure the temple of God and the altar and those who worship there, but do not measure the court outside the temple; leave that out, for it is given over to the nations, and they will trample the holy city for forty-two months.
This passage dovetails perfectly with the temple being rebuilt without the courtyard, because the courtyard area is still under control of Muslims.
