Ad creation for Meta

To Whom It May Concern,
I am reaching out on behalf of NV?Mercantile regarding media production for one of our featured products: the Dual Red Light Heating Massage Waist Belt, available at NVMercantile.store.
We are preparing to launch new ad campaigns through our Meta Ads Manager and would like to begin by testing three creative video ads for this product. Each ad should be 15–20 seconds in length, include a strong creative hook, and align with the NV?Mercantile brand identity.
To move forward, we would appreciate guidance on what materials, assets, or specifications you require from us to begin the production process.
Thank you for your time and assistance. We look forward to collaborating.
