The move would complement Charlton's partnership with club sponsor Redbus Investments, whose deal expires at the end of next season.
"This is not about throwing away our heritage, but rather about generating income and building long-term partnerships that will benefit the club,
said Chambers.
Chambers is looking for a presenting, rather than title, sponsor, meaning that the name of the stadium would not change.
He says he is offering brands access to the estimated 150 million global audience that views Premier League football every week.
Charlton's hunt comes as an unprecedented number of top-flight clubs seek backers for next season.
