"I decided to it's time to stop telling others to start and run a company, it's time to just do your own," Linger said. "So I did - practiced what I preached, I guess - and started my own company."
TMC started out with just Linger and his wife in a room with a fax machine and a telephone.
By 2004, the company had 85 people, according to Linger, and $9 million in revenue, according to a profile of the company published by The Federal Reserve Bank of Richmond.
A healthy chunk of North Central West Virginia's work was fueled by money former Sen. Robert Byrd and Mollohan helped bring to the state.
Linger credits both men and was an outspoken supporter of Mollohan.
"I was a big supporter of Alan Mollohan and the reason I was a big supporter of Alan Mollohan is he brought in a lot of opportunities for high tech businesses to be created and grow in North Central West Virginia," Linger said.
Linger, his wife and his former employees gave tens of thousands of dollars to Mollohan's campaigns and to a charitable organization in honor of the congressman's father.
In 2006, Bloomberg reported Linger and his wife gave at least $54,450 to Mollohan's political committees and TMC and its employees gave another $20,950. Bloomberg also reported that TMC gave thousands to the Robert H. Mollohan Family Charitable Foundation.
Alan Mollohan was the foundation's secretary. The group is named after his father.
The FBI investigated Mollohan's personal finances and his ties to companies and charities in his district. No charges were ever filed and the investigation ended in 2010.
Linger draws a "big distinction" between himself and other Mollohan supporters and tech companies that won federal work. Namely, Linger said he was not "one of those guys" because TMC did not move into a much-scrutinized, mostly empty, multi-million dollar tech park that Mollohan helped get federal money to open.
"I never moved in that park, I never moved my company into that park, so there's a line between being real buddy, buddy with somebody and just being a supporter," Linger said.
TMC did a healthy business as a federal contractor, including millions in work for the National Oceanic and Atmospheric Administration. Linger said TMC helped the agency's scientists more easily access data from four agency data centers across the country.
TMC helped others plan how to capture and store large amounts of data. Eventually, the work appealed to Maryland-based Global Science & Technology, which bought TMC in March 2005.
After he sold the company, Linger started a custom car garage while he was under a no-compete contract. The garage is known, simply enough, as Wade's Garage.
"I assure you, it's not a moneymaker," Linger said.
On Friday, Linger had traveled to San Francisco to do a half-hour repair to one customer's car. He used the already scheduled trip to give himself and his wife a break from the scrutiny - and litigation - Linger has faced since firing Marple. Nevertheless, Linger spent two hours on the phone with Daily Mail reporters, which he said drew at least one glare from his wife.
Between his kids and stepson, he has five children ranging in age from 23 to 32.
After his no-competition agreement ended, Linger started another company in 2010. The new company is known, simply enough, as TMC2.
Linger said his current company does not have any kind of ties to K-12 education contracts, but has done $37,000 in work for Pierpont Community and Technical College.
