PLEASE include baseline budgets so agencies can better plan how you can spend your money to achieve your website goals. An agency will know that with a higher budget, they can spend more time on UX design or an entire digital marketing campaign . If the budget is lower, an agency will know what basic services are required to achieve a successful V1 of the site. Specifying a price range, even if it's vague, is the best way to summarize this, ie $1000 to $10000 excluding tax. When you've invested some time and thought about your report, you'll not only have a much clearer idea of what you want your end goal to be, but you'll also be able to submit that report to an agency, knowing that you need to receive clear cost, timelines, and intentions from them to move your project forward.
