With godaddy, this should work without problem.
1) Before enable the SEF or any other stuff, does the URL and the domain or subdomain can be accesss with success. Does the 500 Internal server error is related to SEF enabled ?
2) Some server (perhaps also godaddy) gives an Internal Server Error when the website has permission 777. In general you should have 755. All depends the owner/groups of the files
3) Which domain, subdomain ?
Is it in a subdirectory of the master ?
4) It is not possible to give tutorial for SEF because this speciific to each server.
Joomla itself provide a htaccess.txt as sample and that must be modified to make it works in production.
This also depends on the SEF extension you are using.
Perhaps you should first have a look in the documentation of the SEF extension you are using and perhaps also to their video.
Setup SEF can take time.
If you want that we have a look to the setup of SEF you can order our billable support
