Baurox,
The main BW issue is mainly the DL/Uploading of all the files to the servers all day everyday we work.
Since I don't know how your business works, the two reasons for this statement that I can immediately think of are: 1) that you might need to move to a colo/virtual server host (assuming that you're hosting the software site at your dwellling), or 2) utilize something like svn/git to do version control (assuming that your workers are making changes to the software every day) at the home office, and nightly updates to the product.
As far as parking goes for your workers, I would advise that you peek in the area with google maps and street view to assess the situation.
Hope this helps!
