Does anybody here know much about IRS tax liens ?

[IneedIRStaxhelp]

I'm a ghost of a poster here and in tax trouble ! They are threatening me with liens. Do any of these tax relief places work or are they a scam ? Can I get a home equity type loan until I sell my house ? I'm about 8k into the IRS and town for taxes on a place worth over 200k but unemployed.

This is a serious thread not a joke.
