My goal this year is to market more to the A/E/C industry. My background is roughly 9yrs (or so) in project administration for commercial Architectural firms... mostly through all phases of design (including CA) - & 6mos was virtually so I know it's possible to do this kind of work remotely.
I currently have 1 commercial GC as a client, but I'm their FTP Mgr. (help with online file storage among other tasks) - nothing exactly relating to project admin. work, but I love them & what I do for them, & hope to add more GC's to my client list providing the same type of support. We'll see...
To sort of answer your ?, if you know what type of support that type of client will benefit from, & already have a good understanding of how the industry works, then there's no harm in trying as far as I see it.
