,I think that contractors who work at the Promenade have to be approved by management, so you will want to check with the office to find out the procedure. The management office mght be a good place to check to see if they can
recommend any particular contractors who have worked in the building and have done a good job. You might also check with other residents to see who they recommend. I believe therre is now a residents listserve. Perhaps they will let you post a query about contractors.
