So, I assuming that you cannot install SQL Server Management Studio. Not even the free version. If this is a onetime thing, I would install the red gate tools. The trial version is fully functional for 14 days. Do your work, then uninstall. You might also check out http://www.xsqlsoftware.com/, they have similar functions as Red Gate. If your database is small, then they have a free option for you. I also like http://www.apexsql.com/.
Use the trial of one of these and then try again to convince your boss to buy one.
