demoing a slab??

[Mike Landry]

I'm trying to get an idea of the cost to demo a slab foundation that was poured but house never built.  between 2000 to 3000 sqft.  Also who or what type of business would I contact for this type of job?  Any other things to consider when doing this?

There are two lots that have abandoned foundations in a neighborhood I am personally looking at building a house in.  I'm trying to use some investor type negotiations to get a good deal.  I have not made contact with the owners yet.  They have been this way for a few years at least and sit on 1 to 2 acre lots in a nice neighborhood.  

Thanks
