Skip Trace monthly subscription?

[Sean C.]

Hello Bigger Pockets,

I have A LOT of returned mail I want to tackle and cold call them. Also, with my limited budget of marketing after sending out my mailers beginning of the month I would be dry the last 2 weeks.

I want to take initiative, and be cold call as much as I could in my spare time which I don't mind doing, if even tracing ALL my current lists in my pipeline and start calling.

I know there are some websites out there like TLO, accruint, and a couple others but I have been informed that you will need a corp/llc set up.

Does anyone know any skip tracing websites that let you do it as much as you can in a monthly subscription bases?
