This afternoon I saw one company about laser cutting and I am seeing another on Tuesday morning to compare laser with water cutting.
I should have prices from them by Wednesday/Thursday next week.
I will then price it all up, including nuts & bolts, shipping etc. and I hope to be able to post a firm price by next Friday evening.
The brilliant news is that since I posted the message yesterday I have had a LOT of interest from round the world - including from the Pi-Less I would imagine <g>
Someone asked about VESA mounting so I have designed, and am having priced up, an optional replacement for the base of the PiHouse so it will fit the VESA screw holes on the back of displays.
Also getting some longer screws to do PiStacks - RPi on top, "things what do" underneath. More info on http://www.ThePiShop.org
