If you can write a good English, you can handle all application procedures by yourself. I did mine many years ago by just following required process/procedures.
The first one was difficult because you had to absorbing all information; after that, it is very easy.
Many patent laywers I knew at that time in Ottawa were driving a BMW with an actual annual income of an elementary teacher.
That's the way how a patent lawyer wants to give his/her client an impressive impression.
Good luck.
