Need VPS hosting for modest website - any drupal-knowledgeable resellers?

We have a modest sized drupal-based website with no bandwith issues. However, because we need port access for UDP data, we are considering moving from shared hosting to a VPS host.
I've looked about, and the cost of VPS hosts is typically much higher than shared hosting and, perhaps more important, requires a level of technical understanding of server settings, etc. that is otherwise unnecessary for our organization.
I am wondering if there are any organizations, resellers, etc. out there who have a full-featured VPS account and would be interested in reselling to us and providing very limited technical support (basically server configuration).
Offers or suggestions as to where we might go for similar services would be welcome.

By the way, our current host is Site5. Just to add to the collection of drupal-specific hosting reviews, I thought I'd share our experience.

We have been happy with the price and features, but have had considerably more downtime than one should expect. In particular, mysql is vulnerable to problems caused by other accounts on the server. It has been particularly frustrating to have support respond that "it's working now" only to have it go down again 1 hour later, evidently the problem not having been diagnosed and fixed. At this time, I've taken to bugging support about every single instance of downtime just to create a track record.
If it weren't for the issue with needing port access, we'd probably tough it out to avoid all the hassle of moving. And we still may not move, we are also thinking of setting up an old barebones desktop to serve as a relay for the UDP data to the website.
