The 7 steps to creating a professional bid are: 1) read the client brief to understand their needs and how your skills match, 2) introduce yourself and your background/experience, 3) provide more details on why you are qualified and show relevant work, 4) outline your bid including the work, process, deadlines, and cost, 5) follow up with additional information, a way to discuss further, and contact details, 6) simplify future bids by keeping templates of successful language, and 7) maintain a professional tone, check for errors, and avoid misunderstood humor.
