Very sorry to hear about this unfortunate experience
@Mesad.
To each his/her own and you know what's best for your family; but I feel that these forms are fairly straightforward and do not need immigration experts. Even if one retains experts / lawyers, these are basic forms, where
data has to be supplied by you and they simply fill it in and submit. Had it been subjective interpretation of Immigration law, defending a case, etc hiring the experts would have made sense but otherwise, I see no real benefit...
I do agree that some things are not super clear but with a few questions on such forums, heal can be obtained...
