Hello, my name is Rissa and I have done plenty of website migrations throughout my career, including into Hubspot COS. This can be fairly straight-forward or slightly complex depending on the size of your website, whether it is HTML or dynamic website, so therefore I would require more information to be able to give a proper quote. However, from past migrations the average charge was between $500 - $1000.
If you can provide more details that would be great. I will get back to you as soon as possible.
Sincerely,
Rissa
