I would like to have a team logo. The team name is greengotts, which comes from the word go green, which means caring about the environment, and comes from the word Gringotts from the movie Harry Potter. I would like help in designing a team logo for use in a marketing plan competition. I would like the logo to be in a modern style and look up-to-date. The team has 3 members.
