Hi,
My name is Daniel I'm new to freelancer, but I have many years of web development and I've recently worked on a similar project.
I will collect and list the data for: Bitcoins, Litecoins, Peercoins, Namecoins and Feathercoin.
If you want to switch or add coins let me know.
I can complete it in maximum of five days, hire me and I will start working straight away.
Regards,
Daniel Lindt.
