U wont wanna be moving a 5' tank once its being set up. As per advised, try to get a stand before starting on anything, even a normal metal one is better than none, unless u jus wanna put it on the floor, but thats quite ugly.
Try the market place, look for sale thread and see if anyone sell jus stand alone, u will be surprised. Alternative method is look into sale thread of 5" tankset and see if there is someone who is only interested in the tank, contact him and u guys purchase the set and them split up the item and pay accordingly.
Good luck
