Design Icons for an online manual

Hi there, We require a series of 7 icons for our small business, which sells real estate services. They should represent "this is an Idea", "this is important", "this is a hint", "look at this", "remember this", "You", "The Client". The icon will be used in the margin of the page where the particular text needs relevant emphasis. The manuals will be provided in an online format. Thank you. We look forward to your bids.
