Answer 1

Knowledge without practical application
So all you know is "Basic Knowledge"?
Please do not say this phrase. It characterizes your infantilism and inexperience.
15k - part-time
30k - full-time
No explanation, so we believe that we have completed the 2nd.
An hour driving, half a day for tests, sessions, dossiting, I don’t know if I’ll be back today, I don’t know if I’ll be tomorrow, calls at 8 in the morning that I won’t come, calls at 2 in the afternoon that I won’t come, I was delayed. Total 15-20 hours.

Answer 2

You open sites with job offers, find vacancies for which you are suitable, take off 30-50% of your salary and get an approximate salary.

Answer 3

Of course, I don’t know the criteria for assigning myself a degree of familiarity with PL or technologies (I’m talking about Basic knowledge markers, Beginner, etc.), but I think it’s better to look for vacancies from your list, look at the requirements, learn about the company and its profile and try add to your programmer's portfolio (GitHub) a few examples of solving problems similar to the activities of the company (s). Then, IMHO, you will understand your worth.
