nginx config file for CPVLab

I need someone to set up an nginx config file for the tracking software cpvlab.com. If you have experience with this, it should be a breeze because it's a one page config file. I have installed and done everything. The problem is that it won't login, (keeps redirecting to the login page) I will need someone who communicates well on skype with me (yes, you will need to do some explaining on why certain config line is written) If you're interested and confident then reply with the word butterfly, all who don't will not be entertained The config file is very important, especially because this is a tracking application and one mistake will cost me a lot of money. So communication is vital.
