Lighthouse Painting: I'm with a Massachusetts municipal park department and have been ordered by the city's administration to "get the lighthouse painted." I know there's far more to it than just grabbing a brush and a can of paint. I need to know how to write specifications for a bid for such a project, as well as how to locate companies that might want the job. Since I'm starting from scratch here, any information or references would be greatly appreciated.
