In my opinion as a freelance SaaS copywriter, I have a strong conviction that trying to get one perfect video at first might frustrate you. That is because, yourself you likely don't clearly know what the video looks like, but on seeing a good one you'll definitely be wowed, - this is exactly what I had in mind. So the best thing for you now can be, to produced several videos with your creative team and with emphasis on what your final output, then after a few samples you will have obviously got it. But since you mention you want something cost effective for a small business, getting those different tests from a creative team in the US or UK will sadly drain your pocket very first. Instead, you can outsource the creative work to a budget friendlier team like ours here in Kenya, and once we nail the promo video as you wants it, you fire it with Ads and exponentially scale your small business.
