Dog Poop Pickup Service

I have a couple of large dogs who produce a ton of crap. I don't mind picking it up (cathartic really), but it really stinks up my trash can and gets maggots while waiting on trash day. This isn't a problem in the winter, but has gotten bad with the heat.

Anyone have a good way of dealing with this? Any services that would come grab the poop bags (or even my trash can) more than once a week?
