I'm doing this for my clients: I research keywords for which they don't rank well, I set up the campaigns, suggest a monthly budget and keep an eye on the campaigns all the time, to fine-tune them. My prices are similar to what you found. But my clients are not affiliates: they have their own products and services to sell. If you really can't find some time for this, outsourcing can be a solution. But I think that the best person who knows his business are you, you have the decision power on how to react at competitors' moves, when to raise and when to lower the bids, what keywords to use or not... and you know when your site is offline, so you can pause your campaigns right away. This is very important, as you may pay for people to see your 500 Internal Server Error, and that does not bring you any money.
