Please recommend styles for these forums

I am looking to convert the following 3 sites either to XenForo or IPB on a tight deadline and don't have the budget for a designer to produce custom styles.

Forum 1
Forum 2
Forum 3

Can you please recommend free or paid styles that look the most similar to these existing styles or that could be quickly customized to look like them?

Please don't include forum URLs in your replies as these projects are on a hiatus and are not publicized right now.
