I have few hundred of customers(office towers, hotels, hospitals, and so on) who have purchased my product and are happily using it.
I would like you to call them all and ask for a feedback and testimonial that I can use on my website.
I will have either pre-written testimonials for them to approve of or you will have to ask them to tell you their own testimonial.
I will provide the exact contact name and their phone number, all you have to do is call and collect the specified information.
I have a heavy accent hence I would like someone who is a native English speaker to do this job.
I will need to use your services for this job every 2-3 months, so this is kind of ongoing.
