While reality TV might seem like a good fit, but reality TV producer Michael Hirschorn has his doubts.
"I think he probably is too crazy even for reality TV. They'd want to know he is going to show up and I think the network would have a real question about that," said Hirschorn.
Sheen has always seen himself as a film actor first. He used his track record to jab his former co-star Jon Cryer, telling E News on Tuesday, "When I'm starring in multi-million dollar films and he's begging me for a supporting role, I'll say, 'You left me out in the cold.'"
Yet it doesn't seem like any multi-million dollar films are on the horizon.
"Charlie Sheen has made a lot of statements about movies he may or may not be doing. Right now there is nothing solid," said Matthew Belloni of the Hollywood Reporter.
Sheen is also reportedly looking into getting involved in selling merchandise.
"Charlie has been talking to Live Nation about putting together some sort of merchandising deal to get some of his new catch phrases - like Vatican assassin warlock - onto T-shirts, etc." said Belloni.
Sheen is also looking to Twitter for income.
Once TV's highest paid sitcom star, Sheen has reportedly inked a deal with Ad.ly to endorse products on Twitter.
Sheen told TMZ his primary motivation for joining Twitter last week was that it's a "cash cow." And, as he pointed out to TMZ, "I'm unemployed."
The unemployed actor was off to a strong start. In just over a day, he attracted 1.1 million followers, setting a new Guinness world record.
Ad.ly's CEO told The Hollywood Reporter that Sheen could make $1 million a year as a celebrity tweeter. That's chump change compared to what the actor was making before CBS postponed his show, a reported $2 million per episode.
Sheen also announced via Twitter that he is launching a live tour starting on April 2 in Detroit, according to the Hollywood Reporter.
Another business opportunity for Sheen has been proffered by Mark Cuban's HDNet cablet network. Cuban described Sheen as "somebody that everybody has a whole lot of interest in who is doing some interesting things, to say the least" according to AP.

With four young children to support, the actor needs money, especially since his spending habits haven't changed. Sheen is reportedly purchasing a new $7.5 million home in Beverly Hills, Calif. According to GQ magazine, Sheen spent more than $1 million on new cars during his first week in rehab last month, adding to an already large collection.
His other purchases, according to GQ, include renting out the Astrodome so "a few friends" could take "batting practice," and paying porn star Kacey Jordan $30,000 for a party he held at his home in January.
Sheen's friend Eric Braun told the magazine that Sheen has so much money he can't "piss it away." "Most people run out of money, they burn out and then they finally hit rock bottom," Braun said, but those close to Sheen worry that "Charlie is not going to hit rock bottom financially." Braun believes "there are just three options" left for his friend: "rehab, jail or death."
Sheen's No. 1 concern, though, is getting back to work. With the future of his No. 1 sitcom in jeopardy, Sheen has said he would demand $3 million an episode from his CBS bosses if they wanted him back. He later told CNN's Piers Morgan he was just joking.
