Working for a company that charges a fee to do homework and assignments for students

Q: I want to ask if it is halal and permissible by law to get paid to do someones homework, college and university assignments, thesis and so on. Students hire us and provide us the material/structure or question given by a professor or teacher and we write answers for them with a fee. I work for the company who provides this service to international students. Should I leave this job or wait until I get another one?

Is it necessary to make intention for ghusal of janaabat?

Q: Is there any niyyat specially for ghusl. I hear people say things like:

Niyyah for Ghusl Bath after having sexual intercourse. "Nawaithu an’ahthasila huslan minal’janaabathi wathahaarathan lil’badni waa’sthibaahathan lis’salaathi ashhadu’anlaahilaaha il’lal’lahu wa’ashadu an’na’muhammadar’rasoolul’lahi.

If I just say that I am taking ghusl to clean myself from janabat, is this okay or doI have to recite the above?
