Hiring a lawyer will usually not help you much, and cost you a lot...
I've talked to a few lawyers for immigration issues, supposedly good ones, none of them seem to really know their stuff. They can be useful in case of criminal issues, or big problems. But for basic stuff, or answers, this forum will be a good place to go to, right after CIC website.
To go through this on your own, I'd suggest you start by learning everything there is to know about EE.
- the different programs, and their eligibility requirements: FSW and CEC and are the main ones
- look into the CRS score system, and what could be yours (you'll need 470+ to be selected)
- look at what documents you'll need, degrees, language tests, police certificates, reference letters, etc.
Based on those you should be able to have a general idea of what your profile is, if you have a chance, what you'll have to do, etc.
The EE process has a lot of details into it, but is also very well documented. If you follow the instructions and get yourself educated about the entire process, it becomes easy to navigate.
Personally, I've read all the info I could find on the CIC website before. I waited until I had all documents, and was 100% sure to be eligible to create my EE profile. I received an ITA a few days later, got medicals done, and submitted my application within a week. For all the things I'm uncertain about, I refer to the Immigration Law texts. This helps clarify things, and be less stressed out.
