Hi,
You may also want to include what sort of money you're willing to invest. Maybe say if you want it semi-portable or may be something more to stay in place for the long haul. Also they have commercial ones and then there's plans. You can make your own if you're savvy with the tools and asking to see other's home made stands may inspire you do to your own. Saying what size may help as well. The more you can offer in terms of what you want, helps... and I know that may be a little difficult if you don't know your available options.. just sayin'.
Good luck,
