Maybe you can amend your application by adding points now for experience you have gained since you applied. If not, maybe you have to apply again. Immigration is big and moves slowly. It's something we have all had to deal with.
If you hire a lawyer, google his name to see if you can find something good or bad about him. If he seems good, you should pay him because he can fix your case faster than you can do it but like everybody, he will not work for free. Everybody needs to make a living, you , me and lawyers too.
