Alan, I just went to check out the gym at Suning plaza next to Galleria/Ikea in the south, and they showed us one room which is basically full of photography equipment (like a small studio) and members can take ‘professional’ photos or use the gear. They also seem to have a ‘per-time’ option, so maybe you could consider heading there, seeing if they have all the stuff you need, and rather than using their gym facilities (or use both :D) pay the gym fee and use the photography studio. I don’t know what stuff they have there, just saw various backdrops, big white lighting things, various type of lights.. they said all their advertisement photography was done in there and it looks pretty good.
6th floor of Suning plaza in the south, same entrance as the normal gym entrance.
