A true booglehead would never pay for that service when it is so easy to do yourself. Vanguard will do a free plan for you if you have 500K with them and then you can follow that plan. Why pay them .7% of assets when you can everything they will do in about 1 hour a month. Fee's kill returns. Adding the .7% to the .2% brings you to .9%, almost 1% in fee's.
A lower cost alternative would be Rick Ferri who does it for .5% and he uses all Vanguard and DFA index funds which are all very low cost. And you need 500K with him as well.
Rick Ferri He has written several books on passive investing, follows the boglehead principals, and runs his own investment management company, Portfolio Solutions.
Personally I would do it myself using my own vs Vanguards plan. I had Vanguard do a plan for me and it was fine, they do the plan for free, but I like others better. I basically use the lazytraders.com 6 fund slice and dice with me own AA. Cheaper, easier, and better back tested results then the Vanguard plan proved to be.
