So I've placed my first order with WHCC, and I must say I'm superbly happy with the results. The die cut wallets are great quality, the 12x18 is very acceptable, and the colors match the monitor EXACTLY. Prices are great, service is great, simple and professional... I couldn't ask for more from a print company, I will be a long time customer no doubt about it.
Since lighting is somewhat difficult to handle with prints, I shot at f/11, 1/200, ISO800, weird angle bounce flash (kinda into the corner of the room), so make your judgements based upon that. 
These are for in-studio use, the 12x18 will be hung on a dedicated sample wall... thus the watermarks.
