Video montage of client testimonials

I have 5 client testimonials, (approx 9 minutes of footage) and I'd like to create one short video ( approx 90 sec) to encapsulate what we offer.
These videos were taken while on a client retreat so any reference about the retreat, ( i.e. the place was beautiful etc) would need stripping out) I'm looking for a short punchy video of the comments saying what it's like working with us and how we work (with subtitles. This needs to be engaging and upbeat.
