Recommendations for a custom cable company

that will make me a 42' cable with mini DP (iMac) fitting on one end and HDMI (big screen TV) on the other end, and 24 AWG copper wire. I am aware that adapters are available such as the Moshi Mini via the Apple Store but I prefer the custom cable.

If you have had a good experience with this or something similar please share it if you would.

Thank you!
Try Drew Baird at Moon Audio, maybe Blue Jean Cable?
Balance Power Technologies? will custom build just about any cable you want. You will have to go to their website to see if they offer the apple connectors.
Thanks to each of you! I will check them out!
