Manuel Ferrara?
 

how much does he get per scene as a performer and is he available for jobs?

I don't know. But, I found this info:

Manuel Ferrara (November 1, 1975, Gagny, France) is a prolific French pornographic actor and adult film director.

Ferrara entered the adult industry in 1997 after winning a competition. He works in both European and American pornography. He was originaly a protégé of Rocco Siffredi, and had an award winning acting career, making his American acting debut in John Stagliano’s Fashionistas. In 2002 he appeared in Snoop Dogg's Hustlaz: Diary of a Pimp. In 2003 he started directing gonzo pornography for Platinum X Pictures, a subsidiary of Red Light District Video. In 2004 he began directing for Red Light. He appeared with Stefani Morgan in Sunny, her first film for Vivid Entertainment in 2005.

After working for Red Light District for 2 years he began directing for Evil Angel in May 2006. His first EA film was Evilution, starring Naomi, Melissa Lauren and featuring the comeback of Nici Sterling. Since then he has directed series including Fucked On Sight, Slutty & Sluttier, Raw, Evil Anal, Battle of the Sluts, Anal Expedition, Teen Cum Squad, Bangin' Black Boxes, Ass Attack, I'm Your Slut, Anal Expedition, Mindfuck, and New Whores On The Block.

I am sure he is unless he is currently under contract with a company like Bang Bros.
I would assume he makes in the range of 800 to 1k a scene.
He is top tier Male Talent.

isn't he exclusive with http://www.manueluncut.com ?

I doubt that, only 3 of the scenes on the first tour page seem to have Manuel on it. I am pretty sure he is a free agent but the money with EA should be good.

Yeah my bro is big money. ;-)
