on time for what?? are you under a levy notice from the irs??
i'm a cpa/cva and i have a masters degree in taxation. . .i doubt that i could do 5 years worth of tax returns for a self-employed person for $810. . .at my hourly rate, that would be 1 hour per return. . .not likely. . .in fact, if your records were clean and easy to make tax returns out of AND you required me to give you a quote, i'd probably use at least 3 hours per return and quote you $2,400. . .i'm very good, but i'm not very cheap. . .however, i'm almost always cheaper than h&r block, and they're morons
