Headshots for students

Hello. We are opening a student accommodation block in London (South Bermondsey) and as one of the events we are looking to give out 30 free professional headshots for the students to use for their LinkedIn socials etc.
This isn't confirmed by our client yet, and if it does take place it would be in October/November time.
All the set up will be there with backgrounds etc. We just need the photos taken, edited (if they need to be?) and sent back to us digitally to give to the student. Thanks.
