Just realized how much we are paying for financial advisor

I am 27 years old and recently inherited about $700,000. My family has a financial advisor through a more prominent firm, but I can not trust the guy. He is charging +2% fee on our total sum. He got a lot of customers, so I feel like he does not have enough time/energy to focus on my wealth.

I have been studying/reading and thinking about doing it by myself through Vanguard's index funds. I'm thinking put majority of my money in couple index funds and let it sit for years without making adjustments. However, I am pretty scared that I'm going to blow all my money.

Some say I should hire a financial advisor, but it seems like FA are all trying to do whatever is in THEIR best interest (although they say that they will be my fiduciary).

Edit: I'm sorry. I don't think I was clear regrading the fee he is charging us. 2% is one time fee as long as I leave it in that designated mutual fund. What I meant by total sum is $ I will put into a mutual fund and after that i guess there are some "hidden" fees. I guess the fee is set by each mutual fund company and he gets a little portion of that 2%.

Stay away from FirstCommand! They sell themselves as "military-friendly financial advisors," but in reality they're just commissioned salespeople.

I thought I was doing the right thing as a new officer for my financial future by promptly going down to the local First Command office and signing up for their investment and life insurance products (they sponsor events on base and their "advisors" are prior military, so they must be the good guys, right?), but it took me 12 years to realize I was being taken for a giant ride.

One of the funds they had me in was so awful that when I went to liquidate it as part of transferring my assets to Vanguard, I found out that the fund had lost so much in value and so many people put in redemption requests that the fund had stopped distributions (TFCIX).

I've since moved all my assets to Vanguard, but I still have $2K in TFCIX languishing back at FirstCommand because I still can't redeem those shares to this day. Bottom line is that you can do a lot better for yourself elsewhere; don't give these guys your hard-earned money.

I went to see one about setting up a private pension because I don't get one through my employer (employed through an offshore company). Got charged about 150 quid for them to go away and "research" some options for me (probably very little research to be done; they already have a standard set of funds that they use through Openwork). For the first year they wanted 35% of my contributions.

The fund that they "found" for me (something Graphene, can't remember the name of it and I'm not at home to check) consisted of several individual funds to apparently lessen the risk of a single fund manager going to shit. In total the funds consisted of about 70% UK equities (why?), had rubbish past performance when compared to a global index tracker and would've cost me well over 2 or 3% per year (can't remember the exact number sorry), plus about 1% per year to the financial advisor for "management" after the initial 35% for the first year.
