Automate Filling out Paperwork
Since you guys are experts with Documents and many people use your service, I believe a lot of companies would pay more if you can automate filling out paperwork.
I’m talking about the Construction Industry, where jobs have to be bid on, and there could be a way to avoid the repetitive task of filling out the same information for all the jobs such as Company Name, Address, Name of President, etc ... All this information can be filled out only once with a user survey. It is a 2 part task. One is answering questions based on a Company Information Survey. The second is actually finding the pages that are required to be filled out, which is stated in the bid package itself.
A whole other task would be to do Quantity Takeoff with Construction Drawings.
If you can actually automate these 2 tasks, you can easily charge Construction Companies $100-$1000/month because this is the job of an Estimator in a Construction Office.
If you are interested in actually creating this, please contact me by email, email@example.com, and I would love to help.
