Ameristar has been having payment "issues" for going on a year now.  I would stay FAR away from them!  I had it out with them this past summer and although they did send me most of what they owed, I am still waiting on payment for a search from July.  You can almost never reach a human being on the telephone, and when you do they blow smoke up your butt and tell you they are "looking into it".  My advice, start collection proceedings immediately.  Do not wait on them much longer - they may not be around by  the time you decide to act.
