recommendations for commercial scanning.

I have been asked by a friend to recommend a place for good quality scanning of primarily colour negatives.
There will be about 250 images on negative strips of 6.
The scans will be used for display on a monitor and possibly for printing after some minor post work. I suspect jpeg will be adequate rather than TIFF.

Can anyone help
thanks
Paul?

I have never used them for scanning, but I get all my prints from these people....... https://dscolourlabs.co.uk/about/Scanning_Services

Very high quality on the print work they have done for me (24x16 inch).
