Go to your city, or county courthouse and apply at the assumed name office. Sole Proprietors pay $7-$13 in Texas to register their business name (dba- doing business as) . Partners pay $15-$20 and it cost me $25 to register my corporation dba with the state.
Call Patrick Jaikaran at 817.478.4470 he is the best CPA I know of. He has customers all over the U.S. He can explain in better and greater detail about setting up your business. He works with small mom and pop businesses, to large corporations.
Hope this helps!
Thanks and have a blessed day!
