Trujillo said the commissioners should stop building projects and then expecting customers to show up using a "Field of Dreams" philosophy.
"We're spending millions of dollars because they didn't plan," he said.
He said developers should pay for new roads and pump stations, not taxpayers.
"I just think we can't afford to have things going the way they are for four more years."
He also said he wouldn't take gifts from special interests.
"If I want to go to a ball game or I want to go to the theater I can pay the $30 or $40 to go there," he said. "There's no reason for me to take anything from them. When you are in public office, as soon as you do something wrong and it comes to light, your credibility is gone."
Trujillo said the commissioners also need to have a better working relationship with the state legislative delegation in trying to bring in new businesses.
He said teacher's salaries and Sheriff's Department salaries should be increased.
He also wants to downsize County Commuter's buses while expanding routes between towns. He said if only 10 or 12 people are riding the bus, the county should have a van, not a bus.
Trujillo said he'd also like to see the county try to subsidize day-care services for student mothers, add police officers and have an "aggressive, zero-tolerance policy" on drugs. Trujillo recommended having correctional officers give seminars in schools on what it's like inside prisons.
Trujillo said he didn't favor raising taxes, and that he didn't know which programs he would cut.
Trujillo attended Cal State at Long Beach where he served as treasurer of his class and Prince George's Community College in Landover, Md. He said he took business management, economics and political science courses and has three years' worth of credits.
He served in the U.S. Marine Corps from 1964 to 1968. From June 1966 to May 1967, he served at Chu Lai and Da Nang in Vietnam.
He now serves as a staff sergeant in the Maryland Army National Guard.
Trujillo also is a member of the American Legion, Veterans of Foreign Wars and Vietnam Veterans of America.
He's also operated his own marshal arts school in Clinton, Md., worked at a paper warehouse in Commerce, Calif., and worked as a voucher officer verifying contracts in the Financial Management Division of the Federal Home Loan Bank Board in Washington, D.C.
Trujillo is one of three Republican candidates who have filed or prefiled for the commissioners' race. A Democrat also has filed, and two incumbents, Democrat Ronald L. Bowers and Republican James R. Wade, have said they're running.
The job pays $20,000 a year.
