TikTok/FB Media Buyer Needed For Growing my SMMA Agency in Mortgage niche

I'm looking for an experienced media buyer to run and manage TikTok ads for multiple clients for our Marketing Agency. We plan to scale it quite rapidly and need help managing all the clients ads. If this is something that can interest you and you're a highly motivated person with a LONG TERM mentality, feel free to send a proposal. If you have previously worked with a SMMA agency and have case studies/examples please link them. The price point is not added yet because I want to keep an open mind and see what the majority asks for and I'm more leaning towards a monthly retainer rather than an hourly fee. This would be a LONG TERM job.
