Specific citation style

[mfWeeWee]

I am searching for a specific citation style. And I don't know where to start.

My professor asked for the entery in bibilography to look like.
Example bibliography:

1. N. Surname1, P. Surname2.....
   Example citations
   (Surname1 2002) or (Surname1 et al. 2002) -if more authors

So first name abbreviation and after surname. Everything I check is vice versa so first surname and after its name abbreviation. I ask you kindly for help.

Thank you.
