Commuting..

[.RJ]

my actual work will consist of Fed clients on-site..

You're going to have to scope out the parking situation, and you may also have a problem having a place to change when you get there if you need to do that - a lot of times contractors get the shaft with facilities. It all depends on where you work, there may be a gym and dry cleaners nearby - just requires some extra homework since you need to look professional each day on site.
