Welcome aboard!
When we were considering building, we looked at as many build threads and blogs as we could find.
We ended up going with Factory Five so we spent a lot of time reading the ffcars forum and build sites that we found there. Although you are building a different make, you may still be able to find some helpful information there, at least as far as looking at other people's build blogs and seeing what is involved and if it's something you still want to do.
As far as how long it takes? It takes as long as it takes. We decided not to make a schedule or put a 'finish date' on ours. Time pressure can take some of the fun out of it, at least for us. I was hoping to get done in a year, but it will end up taking two. But doing our own bodywork and paint added quite a bit of time. And as they say, YMMV.
I have found the build process to be tremendously rewarding. 99% of the time.
