Expired domain question

Hey guys,
I`ve built a website to try to get some construction jobs in the U.K. small scale to do myself.
It has my keyword in the name and is ranking 1st page for the keywords that I need but PR is 0, I dont have many backlinks (directories mostly)

Anyway,
I received my expired domain today from GD. It has PR3 and a few decent links and my keyword in the name. Is a .com rather than .co.uk.

What do you think that should I do with it?
Should i copy the same site onto it? Move the site to the new domain? Or put some unique content on it and just link from it? Redirect?

Any advice would be great, thanks.

That depends on a few things,
Do you like the name more?
What is the link profile of the new site?
Are you only interested in receiving local jobs?

If you were just looking for a higher PR, I would rebuild the site and just link from it.

If you're already ranking page 1 with the old site, why not create new content for the new domain and try to rank two sites in the top ten?

Good shout,
That has got to be the way to go.
Thanks.

redirect one domain do the other and win more
