Self-Directed IRA / Solo 401(k) with Investment Guidance

[Mark S.]

I see several different SD 401(k) and SD IRA companies (with checkbook control) being recommended in the forums which is great but also makes it hard to choose.

Are there any companies that can set up self directed vehicles but also assist you with various types of investments? I would like to use my 401(k) or IRA to invest in real estate notes, tax liens, and perhaps peer-to-peer lending. I'm not yet comfortable with jumping into these types of investments on my own.
