Hi, I am looking for a service that auto- or retweet every tweet from a selected account some hours later. Know anybody where I can find this?
Try RoundTeam - roundteam.co. It is simple to use. They have retweet from Twitter lists feature - it will feet your needs. More about it here: roundteam.co/faq#faq14
Feedburner tweets an RSS feed, it usually takes a couple of hours for the tweets to appear. Not perfect but it may work and the price is right
