What type of website do you have? Most standard websites can be migrated to the HubSpot CMS easily enough (they offer a migration service but if you're redesigning it this might not suit). They have a list of elements that can't be migrated here (some stuff on that list is technically possible but requires some workarounds).
You'll find a few developers on the community (including myself) and can also take a look at the HubSpot Directory or services like OnTheBench.
