Graphic Custom node icons


Hi , only a small job if anyone is interested. I'm looking for a custom node icon for new posts, no new posts and links. I want the circles from our logo found at the top left of our forum pages here

new posts icon to include circles and a orange speech bubble icon in the bottom right of the circles.

no new posts same as above with orange speech bubble faded.

link node icon to include circles with an arrow to the right.

can anyone help and if so what would the cost be?
