Ask them specifically how they get paid. If you are paying a %, generally they also make $$ selling their funds only. In my mind that's not the best situation.
If you all want is planning that usually is a flat or hourly fee.
If all you want to do is beat a ING money market account you dont need to pay anyone. Just look here:

Either way, do some reading or you could be taken by an 'expert' looking to pay his rent.
Good luck
