Design some Business Cards

I am looking to update our companies logo, security sign, stickers and business Card. The sign and sticker will look the same but the graphic should be able to scale, the sign is 8.5x11in and the sticker id 3x4in. The sign must have the company Logo/name, licence number and phone number. The front of the business card should have the company name/logo, employee name, employee email address and business phone number. The back of the business card should have a description of the type of work that we do ( Structural & Perimeter Security Systems, Surveillance Systems, Access Control, Structured Network and Media Wiring, System Integration), the contractors license and alarm license numbers, and the companies mailing address. Attached are pictures of the current sign, stickers, and business card. We would like to keep the color scheme black and yellow, or similar.
