Need Feedback on WebAppHelp company

Has anyone used the services of WebAppHelp [.com] ? It is a service company that offers WP support services.

I am a blogger at a small start-up. We simply need someone to maintain a WP installation (upgrades, security patches, theme install / config, etc.) The Idea is to have someone do all the technical tasks so we can just write and promote the blog.

Any feedback on this or similar services will be great!
