The good news is without an IT department you can often get a lot more done.
We had one client that was trying to get a file from us. Their IT department had everything so locked down it was impossible. The client grabbed his personal laptop and went across the street to McDonalds and download the file. It took him six months to get his IT department to put us on a list of approved providers so we could send a file to his IT department and they could send it to the end user.
