We have setup a demo online and close to finish it today.

The demo is at http://demo.coinsofts.com:3000/

We currently use same UI as bitdoubler.org because we are sure if you build your own, you will change the UI.

More technical details:
Client side is made with AngularJS/Bootstrap so it is both desktop and mobile friendly.
Server side is made with NodeJS/MongoDB so it is light-weighted and fast.

For price:
We sell it at 1btc including
1) full source codes (angularjs/bootstrap/nodejs/mongdb);
2) setup for you for free;
3) free 2 extra hours supporting.

As asked by some guys for lower price, we now accept .5 BTC for just 1), if you need both 2) and 3), we have to ask for 1 btc.

Thanks
