Online forms

Give a dog a bone! I have been researching (or rather, attempting to research) methods for posting online forms. Using Adobe Writer / Acrobat is painstakingly slow and I know there has to be a better way! Question is, what is it??? Has anyone had any luck with this process either through software or a service, perhaps custom solution implemented? I am currently re-designing our website to include an online, searchable, document warehouse and want to give users the ability to fill out all forms found within, but as it is, the job will take a tremendous amount of time! Any suggestions???
