Where are the sources to do commercial/industrial real estate research?

[Peggy Liu]

Does anyone know of good websites to find out the market statistics for commercial and industrial real estate?  Currently, I'm googling for information online to find out who the builders/companies are for new industrial construction in southwest Las Vegas.  I went on Colliers website and they report how many square feet is under construction for this year but I need to know what kinds of companies are building them and what are these industrial spaces going to be used for.  Is there a source I can go and find out this data?  Is there some kind of press release that would have this info?  Thanks!
