Simple Letterhead, intro letter and email signature

Information for the business: Arts Management
Industry: Business
Design details: I already have my logo and business card designed so I pretty much just want that replicated on letterhead and email signature, with some consideration on layout and review the font choice (its black and white, so no need for colour selection). I have some additional copy for the Intro letter/promo (to be supplied separately) that I'll be using to introduce myself and my business (via email), so I would like a lot more design consideration for this, but should relate to the letterhead design (and other designs). I'm after a clean, contemporary and sharp design. Please outline in your proposal the number of designs you will do for the fee. Proposal should include a short explanation of your thinking behind each design and/or design choices put forward. Final delivery should include Microsoft Word template file and PDF editable template file (email signature, PDF and PNG).
Ideas for the visual style: Black and white. Clean, contemporary and sharp design
Extra notes: Logo font is Alte Hass Grotesk - which I'd prefer to stay with for consistency, but I'm open to suggestions/comments
