First of all, your website loads very slow for me and I know it has nothing to do with my connection.
Second, you're charging pretty hefty prices for advertisement on a website that has no traffic. Those prices are in Bitcoin right?
You're asking 1 BTC for ads on the top of the grid, 0.10 BTC for the middle and 0.01 BTC for the bottom, way too expensive.
How are you planning on driving traffic to your website?
Slow loading - yes, requires time to load 100 images.
Yes, prices in BTC, and we will change them to low. Main idea - to sell these bricks at any price to start trading between users. And users would set any price.
We plan to use AdWords to promote site.
Thank you very much for your feedback!
