How do I send a database to someone else?
Select a.name, b.physical_name 
from sys.databases a 
join sys.master_files b 
    on a.Database_id = b.database_id 
Where a.name = 'NAME_OF_YOUR_DATABASE'  


This will show you the location on disk.. (can't move it though). 

Backup the database:

BACKUP Database NAME_OF_YOUR_DATABASE
To Disk = N'C:\Databases\NAME_OF_YOUR_DATABASE.bak With Compression
