PDF fillable forms for clients on phone or other device

Hello, I am not a coder or anything. I am a solo practicing lawyer. I am trying to find a solution to my problem. I need clients to fill out a PDF form that I have created and then send it back to me. I then export the data and import it into a different PDF. A few issues have come up. One, many of my clients don't have email so that eliminates just sending them the PDF via email and then them sending it back. Two, even if they have email and then either a phone or computer, I have noticed that many clients dont necessarily have Adobe Reader and so then fill out the form in their browser which changes things. When I export the data it doesn't do so cleanly. I was hoping Adobe had some sort of eco-system that the client could get to the form via email or a link and then fill it out there (like Adobe Forms Central?). I have looked at work-arounds such as Google forms zapped to google spreadsheets to the PDF but it seems very complicated for something that you would think have an easier solution. I tried sending myself the form via Adobe fill and sign but when you sign and then receive the PDF back it's flattened and you cannot export the data. 

Any solutions the gurus on here see that I don't? 

Thanks, 

Joe
