Anyone want to aerate?

We've got an infestation of poa annua in our lawn, and we need to aerate. To rent an aerator from Home Depot is about $45 for four hours. Anyone miss aerating earlier in the spring that needs to do so now? We'd love to split the cost. Ideally we'd rent it tomorrow morning, but we can be flexible. Let me know by leaving me a comment or emailing me at chelsey DOT jorgensen AT gmail DOT com.
