I did it myselft. Do you have LC?
I did EB2 (NIW) myself but in my employer's name. NIW is a bit complicated but I went ahead myself since most the recommendation letters have to be prepared yourselves even when you have an atoney. I got a request for additional evidences and I responded. so far no result yet.
after I received my LC early this year (I did LC myself too), I filed I-140 again myselft but in my employer's name. No result yet. in both cases, my employer paid the application fee.
