I need to be able to post clients' work on line somehow and portray samples of my work - anybody know who is experienced and reasonable at building a web site of this sort - or what are my alternatives?
It isn't difficult to post VR files onto a web server and there are page templates available from the likes of Garden Gnome (Pano2QTVR) and DevalVR. Is cheaper than paying someone else to show your stuff and much more satisfying to do it all yourself. However, if you want to show a complete VR Tour, then maybe using a program like Tourweaver from EasyPano would be best, this would output all the files needed for upload and can do a lot more besides.
I have gone for the DIY method, for VR Tours and the single file full screen things, but then I only have myself to please. So to an extent it depends on what you want to do what way you jump.
