I don't like the font used on Signs & Designs. Just doesn't look quite right. I am sorry I can't offer an alternative.
Agree with Jill. Perhaps a white background- the lime greens really look good with white- and it would be "friendlier"To be honest, it has a very generic, "computery" feel.
Definitely make Signs and Designs a bolder font, perhaps a serif font, something more friendly/less cold looking.
What you do (to me) is more important than the name.
Love....Jill
