Probably, though the useful answer depends on what you need it to do. Describe the project and you will get a straight opinion, including if it is not a good fit.
How long does a project like this take?
It depends on scope, and it is set out in the proposal before anything starts. Work is usually rolled out in phases so you see progress rather than waiting for one big reveal.
Do you rebuild existing sites or only start fresh?
Both. A good part of the work here is taking something dated and moving it onto a footing that can be maintained, without losing what already works.
