Dear [name of lawyer],
I've worked a number of years in an asbestos-laden environment. My health is failing, and though doctors don't have proof of what's ailing me, they think it could be mesothelioma.
As you know, this form of cancer is as difficult to diagnose as it is to treat. I need to provide for myself and my family in the interim, and I require the means to pay my medical bills.
I'm interested in getting a consultation on this matter. Do you provide these free of charge? If not, can you recommend a lawyer that does?
