Paid ads specialist needed — thirty-day launch engagement, Canada and US SaaS

We're launching an accounting and ERP platform for small and medium businesses in Canada and the United States, and we need a paid advertising specialist based in Canada or the US to run our launch campaigns. Scope is paid media only: paid search and paid social strategy, account and campaign structure, ad creative and copy, audience and keyword research, conversion tracking and attribution setup, and ongoing optimization with clear reporting. This is a paid thirty-day discovery and setup engagement to start, with a continuing arrangement available afterwards based on results. We have a product website, a hero product video in production, and additional creative assets in progress. Ideal candidate has demonstrable business-to-business SaaS experience, ideally in accounting, finance, or business software. In your proposal, please tell us what you'd want to learn in the first thirty days, what test budget you'd recommend to get a statistically meaningful answer, and how you'd measure success. Include two or three relevant case studies with real numbers, your rate for the thirty days, and your ongoing retainer if we continue. We'd also welcome your ninety-day thinking, though we're only committing to the first thirty at this stage.
