Real Estate:
I estimate 10-20$/room depending on how big the house is. If it is a lot of rooms, the estimate per room would be on the lower end.
Videos:
Depends on the situation but it would be at least 120$ as my base rate for a 1-5 minute video.
Photos:
Google Business Photo: 60$ for first photo and 40$ to update it.
Anything else please contact.
Virtual Tours:
Contact with your idea for anything like a virtual shop or gallery, educational content (my software is compatible with a LMS like D2L), safety training, gamification, etc.
