I'm available February 4th from 10am-11am.  Rest of tax season - nope........

Actually, if you're looking for just data entry you could always get an accounting student at a local community college or as I've done, a high school student that wants to go into accounting.  Downloading, sorting of documents, data entry might all be of interest to them and in high school they can earn credit.  I would make them employees and in-house for the work and the training.
