I currently have a contractor working for me via an agency. The contract is rolling on a weekly basis and I can end it whenever I like.
I have suggested to the agency owner that I could prepay for development services for 3 or 6 months if a discount was offered. The owner seems to appreciate this idea as it will allow him to scale his startup agency. Neither of us has mentioned the discount percentage.
What is a reasonable starting discount to request for each of these periods?
I've read this but I'm not sure it applies here as it's 2 days a week and therefore considerably less money.
