Modification of Corporate Identity Package using Adobe CS3, AI, and In Design

Design details: We purchased a corporate identity package, but need to modify the logo name slightly to fit our business. We also need to modify the other elements including business cards, letter heads etc (All elements where logo was included)

Attached is a copy of the business card. Where the name is Avanti creative, we are called avanti accounting. There are approx. 10 print elements that need to be amended. Also need to modify the text / addresses etc where required
