Running the service costs $100 / month. But me having to work on it full time for free. Successful number of jobs is around 70~80%. sometimes bad extraction is also caused by the user labeling things incorrectly. Say my hourly rate is $30/hr, I end up spending 10 hours, $300, fixing one user's bad extraction. My hope is that this fix will transfer to other user's encountering similar bad extractions. The smallest plan earns $30/month. From this pattern I can see that what the average user pays won't cover my time spent on fixing bugs with the extraction system or maybe this is an early assumption? Also about 10% of bad extractions are simply impossible to do with just software alone, it really requires human to intervene and do it manually (something I can't do because it takes so long).
