She’s taken meddling motherhood to a whole new level.

Geri Brin is so anxious to marry off her 31-year-old son, Colby (pictured), she’s launched a Web site where she and other parents can find perfect matches for their single kids.

“I’ve been fixing my son up for about five years,” said Geri, an Internet entrepreneur who works with Colby on the Upper East Side.

“I even set him up with the saleswoman at the upholsterer I used to re-cover my sofa. I figured I might as well cast a wide net to increase his odds of finding the right woman since he’s not hitting the jackpot on his own.”

Colby is not at all surprised by his mother’s latest project.

“One thing about my mom,” Colby joked, “she has perseverance. I can picture her on her death bed . . . choking out the words, ‘Colby, did you call that girl?’ before fading into darkness.”

“Literally,” he said, “if she hears of a single woman, she’ll mention it to me. It’s almost like a synapse in her brain that’s been conditioned to automatically fire.”

Once his mother set him up with her dental hygienist’s friend’s daughter.

He schlepped all the way to Queens, like “Indiana Jones on a great adventure, hoping for a pot of gold at the end of the rainbow,” he recalled

He was greeted by a father who initially slammed the door in his face and a date wearing “makeup two inches thick.”

Colby isn’t the least bit embarrassed about being fixed up by his mom.

“Look, I’m a Jewish guy who grew up in New York,” he said.

“Obviously, I’m a momma’s boy. Who are you kidding?”

Besides Geri’s personal interest in the site, she believes it’s a unique business opportunity.

“I thought, yeah, I’m starting a whole Web site and investing hundreds of thousands of dollars just to fix my son up,” she laughed.

So far, she’s attracted 20 parents and their adult kids to sign up. One of them is Susan Grant, a merchandising manager for a jewelry showroom. She said the beauty of the site is that it’s the moms doing the setting up.

“All the kids have to do is roll their eyes and blame mom for getting them involved,” she said.
