Logo (+business card, memo, envelope)

We need grahic design for new e-learning company. We are located in Croatia. We need 3 COMPLETELY DIFFERENT logo proposals. Logo should consist of some abstract graphic element(s), we dont want it to use some symbol that associates with learning or teaching. _________________________________________________ Please, read detailed guidelines in attached file. _________________________________________________ When we choose which one of 3 logos we like best, then you procede to deliver in same style business card (2-sided), memo and envelope design. We will be needing also web design and brochure design for this. So, if we develop good collaboration it is very possible that same provider will be assigned to design after this project also web design sample and brochure. This will be separate project, just writing to emphasize that we are looking for possible longer collaboration.
