Is there anyone available to help me with my past tense grammar in French?

Question

Good evening all, I have an assignment for French and would like either an advanced or a native speaker to analyze what I have written. I am working on past tense verb usage and I am struggling a bit. It is an essay, so I figure it may be a bit extensive to post on here.

Answer

Bonsoir Malahni,
What I am hearing you ask for is a tutor to assist you in advanced past tenses (i.e. more advanced than simply le passé composé or l'imparfait).  While I am unable to answer for anyone else, I have never seen academic assistance, or tutoring, provided on this site.  
Here are links to three different online French tutoring sites:
https://www.tutor.com/subjects/french
https://www.wyzant.com/French_tutors.aspx
http://onlinefrenchtutoring.com/
Now, let me say that I am not affiliated with any of these 3 sites in anyway; however, one of them might give you a place to begin seeking a tutor.  As you do not indicate in which city you live, I would suggest that you first begin there by possibly looking through the yellow pages under the heading «Tutor».  
Désolé !
Bonne chance.
