Nice Icons.
Thnx!:)
You can offer services and products in this website???
Without being the official last word on the topic, I believe the policy is that promotion of this kind is permitted as long as it stays in the appropriate sub-forums, like "Your Announcements" as this one is. However, spamming, promoting things that aren't related to game-dev, shilling out your affiliate links, and other such nuisancery isn't tolerated in any forum.
When in doubt, ask a moderator.
