Design a "we have moved" card for a law firm

Information for the business: Small Civil Litigation Law Firm
Industry: Legal
Design details: Looking for a post card or single piece announcement that will inform that the firm has moved to a new address but that all other info had remained the same. It should have short blurbs about the attorneys (e.g. Joe Blow formerly of Dewey Cheatham and Howe) at top of announcement with a listing of the staff names below. Nothing flashy or too busy. Graphics should be clean and neat and only be used as accents rather than focal points. Borders would be welcome to frame out the announcement. If the file can be created with a commonly available program and sent to me for final text addition/editing, that would be preferred (i.e. use common program with text boxes etc. pre-formatted so that I can click and edit).
Content to include: Name of Firm, Attorney names, staff names (to be supplied), blurbs as to attorneys (to be supplied)
Ideas for the visual style: Scales of Justice, Courthouse steps, Legal Books, NY City Skyline
Things to avoid: Judge Judy, script or flowery print styles
Preferred colors: Forest Green for Firm name, other print at your discretion
Extra notes: Times New Roman is preferred font.
