It is a Yes. I recommend an immigration lawyer. The lowest possible value is that one gets advice but then acts on one's own. The highest value is that it is turned totally over to them and everything gets done perfectly and timely. Better to know that everything possible was done than to look back later and wish that it had been done. One can argue after the fact that one could have done it themself. However, one cannot argue after the fact that they wish they had gotten an immigration lawyer. The goal is to get the visa, regardless of knowing or believing afterwards that one could or could have done it better on their own. Keep in the mind the goal, and not necessarily on the whos, hows, or whats on achieving that goal.

And it is suggested that it is better to get an immigration lawyer based in the target country, in this case, The U.S., and if possble in the immediate area where the sponsor is located. Experience, expertise, location, and ability to respond immediately all can help reduce the time frame.

If there is anything that is not understandable, not just what I have written, but any documentation or notes related to what you are trying to achieve, move it into something that is understandable. For example, one can take the text I wrote yesterday and copy and paste it into a Word or text document, then enlarge the font, etc. Just do whatever has to be done, whether it turns out to be very easy or very difficult.

Wishing you well.
