More than 600 businesses want in on the action with President Donald Trump's "border wall" — including one from Mexico.

Ted Atalla runs a small business selling LED lights called EcoVelocity based in Puebla, Mexico, about an hour and a half outside of the country's capital. He said he was born in Egypt and immigrated to the United States as a child. After many years in California as an American citizen, he moved to Mexico about five years ago and counts himself among Trump's supporters.

"I've been defending what we've been doing over there," he told CNBC. "I think it's a good thing."

But Atalla said he doesn't expect to win any work on the wall: His LED lights are made in China, and that's unlikely to go over well with the administration's mantra of buying and hiring American.

"I'm just watching [the contract] to see if I can offer anything to anybody when it comes," he said.
