After some months of work, we finally are able to have our first shop online, with domain names sales and management.
You can see this on the KalyHost page for domains, where you can order many extensions for cheap (.NET are on sale until 27 february).
Sale is done via Paypal, and domain is usable immediatly after sale. You can then manage your domain as you want to. Once we finish setting up webhosting and some other services (affiliation, etc) KalyHost will finally be ready for the real show. For now cheap domains are already a great thing, and I wish more people could have a look at it.
