I need a logo design for "ecoleave". ecoleave is a brand name for e-leave web based management system. The message of this brand is eco-friendly paperless leave application, approval and reporting. The color should be similar to green plant that is very lively, healthy and growing. Please propose a slogan for this brand as well. The brochure come with 4 pages of A4 size. I prefer to have 1st page as an ecoleave concept with pictures, eleave logo, title, Facebook, twitter logo and link, as well as QR code of our website link. 2nd page will have a summary of eleve with features and selling point. 3rd pages will be reporting with screen shot of eleave system. 4th pages will be reason to buy from us and contact details.
