I'm not a professional, but I am learning from posts in this forum and I hope you will accept a suggestion from an amateur.
The Calumet background stand set looks like a good deal. If I lived in the US I would probably buy one. Living in Thailand on a limited retirement budget that isn't really an option. The only background sets I have found are massive and expensive ones for professional studios. I wound up making my own portable background.
I wanted a portable black background. I found a very inexpensive 1" diameter corrugated aluminum tube at my local hardware store here in Bangkok. It comes in either 4 or 5 meter lengths, I forget which. It is used for everything from mop handles to curtain rods or closet rods. I bought a 2 m section for something like the equivalent of $3-$4 US. I'm sure you can find something like it anywhere in the world. I know I have seen rectangular corrugated aluminum tubes sold for closet rods in the US.
I drilled a hole through in each end of the rod so that I could put a 1/4x20 bolt through it. I can now replace the normal strobe light mounting studs of two light stands with female spigots and simply bolt the rod to the stands. Alternatively I can either put in a pair of eye bolts, or just use the drilled holes, and hang the rod from something like a draperies rod with wire hangers or even string.
I bought a 3 m piece of deep black 65" wide fabric for less than $15 US. I glued seven Velcro hook tabs to the rod and sewed seven loop tabs in matching positions to one end of the fabric to hold it on the rod. I next added different colors of cloth, with the Velcro tabs, so it is easy to change the backdrop color. If To take the backdrop somewhere I can simply roll the fabric background cloth(s) of choice up on the rod and slip it into a homemade cheap fabric sleeve for protection.
Here is snap of the end of the rod with the black cloth rolled up on it in the fuzzy background.
The biggest problem with this portable background is the length - it won't fit inside a taxi for instance. I found that I could buy a PVC pipe straight joint that was an almost perfect fit. If necessary I can cut the rod in 1/2, glue the PVC joint to one side, and hand carry it in two 1 meter long pieces with a folded background cloth anywhere.
I also made a jointed 4 meter rod for the 12' x 10' ugly wrinkled blue muslin background cloth I already had, but did away with the Velcro. I simply bulldog clip the cloth the that rod.
