Forwarding an Entire Domain

Hi There

Have a succesful business but unfortunately had a gentlemans agreement last year with an unscrupulous person who basically wanted to suck value from it without actually adding much at all. We now want to work with somebody that is actually willing to help us out but have found out we either have to disband the business completely or buy him out for a ridiculous sum that none of us can afford.

We are thinking of just completely disbanding the business to get rid of him but, if that was to happen, we'd need to host the site on a brand new domain name. The domain has some age (just over two years), a lot of really good content and quite a lot of back-links pointing to it.

Thinking of buying a new domain name and basically mirroring the site. Keeping all the same page titles etc. and just r-writing the content on it and also 301 re-directing every page on the old site to it's corresponding page on the new domain.

I get about 40 enquiries per month at the moment. Will I see a significant drop in enquiries now if I do what I've outlined above as it will be a brand new domain name. I know that I'll lose around 10% of the link juice. Will domain age be a really big factor in all of this?

Thanks,

Dave
