Anodizing or clear coating cast aluminum boat hatches - need expert

In the Washington, D.C., Baltimore and eastern shore of Chesapeake Bay area, I am looking for some shop that can anodize or clear coat some boat hatches I have two large (2' x 2') and four small (10' x 10") lifting hatches on my sail boat. They are made of cast aluminum and they surround tinted plastic windows. The cast aluminum was painted white back in 1988, and is now flaking off of both upper and under surfaces. I wish to remove the white paint and then anodize or clear coat the aluminum frames. I sanded the white paint off of one hatch, and liked the bright aluminum look - - and thought perhaps it could be anodized or clear coated - - and thus resist the damage caused by constant exposure to sun and salty water environment. I found, however, that I didn't have the appropriate experience or tools to properly remove all the paint, and to make sure the aluminum frames around the plastic hatch windows were properly and neatly done. Anyone out there who can take on such a job? Or give advice? Thanks.
