self directed ira help

[John Lindenauer]

is there a company that provides the ability to invest in traditional stock as well as non traditional. My goal is to invest in the market short term with a 401k I wish to rollover then, when the opportunity presents itself, I wish to invest the money in real property.  I wish to keep the money in house so I don't have to have multiple accounts simply to save time and for ease of transactions.

Thanks for any help
