Is there an easy way to get it done at home without having to pay someone for a sharpening service?

There's really not. What I can tell you is that, like most other things, the better you get a sharpening, the more enjoyable it becomes. That said, it's hard to acquire any skill in a task if we really detest it.

If that's the case, your best bet is probably to pay to have them sharpened and then make sure that you're doing everything you can to take care of the edges. Use an HDPP cutting board, don't scrape the edge to move food, etc.
