Durojaiye, a Nigerian who was called up for his country's under-20 development squad, played in the National League South for Welling United last season.
He started his career as a youngster with Tottenham Hotspur and Norwich City, before joining Scottish sides Falkirk and Brechin City.
He has also played non-League football for Enfield Town, Hayes & Yeading United, Hungerford Town and Haringey Borough.
His time at Tottenham saw him rise through the ranks to the under-18s as a striker.
He then trialled with Cheltenham Town, Brentford and Oxford United before moving to Norwich City in August 2012, where he signed a professional contract.
In July 2013, Durojaiye moved north of the border to Scottish Championship club Falkirk, spending two seasons at the club before finishing the 2014/15 campaign on loan at Scottish League One side Brechin City.
After spells at Enfield, Hayes & Yeading and Haringey, he signed for Welling in August 2017.
In addition, Quinton has agreed terms with Nathan McDonald, Billy Crook, Marcel Barrington, Luke Allen and Dan Thompson from last season`s promotion-winning squad.
