Lien research by myself in TX

[Corbin Blackwell]

I am trying to figure out an economical way to search for liens on properties up for foreclosure in TX. I would need to search 100-200 properties within a few days. The online county document database is not up to date with the current month's foreclosures so I don't think that is an option. Has anyone had success searching for so many properties in such a short time frame and if so how?
