Be a good messenger  and take to lawyers and law firms the good news: a really inexpensive tool that will help them  work more efficiently , spending their time on billable work instead of squandering around searching, copying, filing etc.
Plus, LawRD will pay you to do it:  $3.5/€2.5 for each user ,  every month , for  10 years !
 Sure you know lawyers  and people who know lawyers. Just go from there and you'll see that soon you're  making a nice extra . Before you know it, it might even become your main source of income - it's really not that hard.
