Assist me with Bulk Marketing

We are setting up a crowdfunding business and we are looking for a firm/contractor to design and implement a marketing campaign on our behalf, in order to find the right audience. He are a financial business regulated by the Financial Conduct Authority, and we have restrictions in regards to marketing to general public. A person/firm with knowledge in the finance industry would be more suitable to partner with us, however, this is not a 'must have' requirement.
