Social Media Manager (2x Pre-Launch Campaigns)

I need a social media campaign manager to run 2x pre-launch campaigns: 1. A unique, luxury protein supplement is going to market in 2x months. Goal: Build email list and education 2. Fiction Novel: Give away first 2x chapters to build email list for sale (going live in 2 months) Campaign manager would need to set up social media accounts, manage via something like planable or buffer. Manage email list growth and email engagement via MailerLite. I will create much of the content but if you can also create content, that would be very helpful. Successful management of prelaunch campaign will result in continuation of the contract through launch. Please send me examples of similar work and estimated costs per campaign. Thank you for your interest in this project and I look forward to working with you.
