Solo 401k intermediate suggestions?

[Sean H.]

I need to open one up before the end year. A quick search yielded me mysolo401k.com. They charge 425 to start up an account, and 125 a year for maintenance. I will probably start doing the maximal 57k contribution for this year, and every qualifying year after. So, i would rather it be a flat fee. I want to be able to loan the money to other investors, so i don't want to setup up through companies like fidelity where you can only invest in other fidelity funds.

Any suggestions on how much i should be paying or other suggestions?
