As others have pointed out, this is a very personal choice. One that could have very important implications. So think through very carefully.
This being said, I'll share my personal experience for what it is worth.
We engaged a lawyer (Canada based) for our 2014 FSW application. We ended up having to 95% of the documentation work ourselves--some of that, rightfully so. But, in other instances (e.g., review of letters of reference), we weren't guided properly at all. To boot, this was a pretty reputed firm. We were told our job titles have to match word-for-word one of the job titles listed in our pertinent NOCs. Because of this, my spouse's employer refused to give a reference letter--citing reservations about attesting a job title that does not conform to the real one. Because of this, we provided a self-written letter with a lot of documentation (pay stubs, tax returns etc). We repeated asked the laweyer if this was a safe approach. We only got canned responses--it's up to the visa officer. It eventually didn't matter because our application was returned due to cap limits. However, knowing what I know now--thanks to this forum--I am confident that our application would have been rejected if cap was still open. Many of the supporting documents were very shoddy. One good thing that we got out of that experience--a good cover letter template for the LOE which I used for our EE application
.
No one else but you--not even a paid attorney--will be as dedicated to your application. My humble suggestion is that you go through the "Reasons for Rejection" thread carefully and start your prep work from there. I wish that this thread had been around when I applied; it would have saved me a lot of time spent trawling through various threads to figure out potential red flags. It's a treasure trove of information thanks to the generous folks who have taken the time to share the reasons for their applications being rejected. You'll be able to identify exactly what you need to do and, more importantly, what NOT to do, to put forth a solid application.
And, perhaps best of all---posts by Asivad. No lawyer/consultant comes close.
Hope this helps.
Good luck!
