You can easily add me as a user to your account, with view-only access. After my job is done, and I've created a reorganisation, optimisation plan, you can easily revoke my access
I only need to know what is your main marketing objective, e.g. what are you trying to sell or what you want your customers to do when they see your ad / who do you want your customers to be.
Marketing plan / improvement plan is usually ready in 12 hours, but as fiverr offers, 1 day is fine.
