trying to find the right form that was not already filled out. Also you need to add the ability to erase to the lowest membership level. You can do a couple of things such as restrict the number of new forms per month, offer a 1-5 form only fee, or only a 1 month membership fee. In the past 3 years I've used this service only twice now as I am not a business.

PDFfiller.com has been the most reliable and simple piece of software I have used for this type of work in a long time. Adobe has made things quite expensive and your product has been the lifesaver many times. Simple to use, end product is of high quality. That is what I was looking for and found it on PDFfiller.
