Video Slide Production for Facebook Ad

Do you have experience sequencing still photos to music and captioned text? Assistance is needed to finish in excellent form a "video" for a Facebook ad. The "video" is made up of multiple still images, (and one brief, seconds-long actual video clip). I've recorded a voiceover, and I need a few adjustments made to images and captioning so the finished product may be included in an ad in the next day or two.
