Social media posts and ads for US mortgage company

My company is interested in working with a freelancer to create social media posts and ads that focus on US mortgage services. We would like these posts and ads to be created for platforms like Facebook, Instagram, Twitter, and LinkedIn. We are hoping for the tone of these posts and ads to come across in a friendly and approachable way - not too professional, nor too humorous. Our target audience for this project is real estate investors. If you have experience creating social media content and feel like you can produce content addressing our needs, we look forward to hearing from you!
