Legally is rare- they want to pay bribes for you.At one time connected lawyers did it legally with political pressure.
Otherwise why would they expedite your app just because you paid some guy money to apply for you?
Immigration has asked you not to apply in this way.
The best person to expedite your app is an employer who convinces them that no other person can do this and they need it done right away as in high school teacher or PHD biologist or Vet....or oil spill cleanup expert.
