Marcus Lemonis, the entrepreneur, investor, and star of CNBC's hit series The Profit, isn't afraid to call out executives when they need a good reality check: "You need to stop acting like you're the only one who can hire somebody," he says to Shereen Mahoney, the CEO of Brittenford Systems.  

Mahoney, whose business saw revenues of $4.8 million in 2014 and is currently on track to increase that number by 30 percent this year, appeared as the featured business owner on Tuesday's episode of Ask Marcus Lemonis. Each week on, Lemonis talks shop with an entrepreneur, and answers one question about his or her most pressing business challenge.

Brittenford Systems, based in Reston, Virginia, implements accounting technology for third-party companies. It has 28 total employees, eight of whom were hired since July of this year. Mahoney explains that she takes it upon herself to find the right talent by browsing LinkedIn and by posting advertisements.

She adds that she's concerned about growing her company, as not enough people seem to have the technical savvy--and the familiarity with her systems--that she requires. 

"How do I best attract and recruit top talent, ideally without having to use a recruiter?" Mahoney asks.

Lemonis is frank with Mahoney that she really does need a recruiter. "You're just running out of human capital, and it's irresponsible of you to think that you're going to be the only one who should do that [hire workers]," he says. 

For more on how Mahoney can find the best person for that job--and potentially increase her revenues to $7.8 million--watch the clip above.
