Promotional Videos

We are a city and guilds training and education centre for animal welfare and pet grooming coupled with business development training. We empower people with the qualifications and skills to change their career/life and go on to run their own successful business. That can be an at-home set-up, a mobile business or a Salon/boutique. We have been very successful and we have a new Website due for Launch at the start of February, which needs extra video content.

So in a nutshell we need to start with two types of videos required for internet viewing:-

1. Exposition/promotion of our business (Here's an example of what we are looking for https://www.youtube.com/watch?v=QOZmFZFAWx0 )
2. Three or Four On-site testimonials (around the M25/home counties) that are more than just talking heads (there are some nice customer success stories here: https://www.upwork.com/i/stories/ ).

We have more requirements but for now let's start with this.

We are based just off Jn 22 of the M25 in St Albans in Hertfordshire
I need ideas, portfolio references and a breakdown of costs, availability and turnaraound time.
