If using remodeling comp. on 1st flip, interior designer advise

[Chris Melear]

Im using a remodelor/gener contractor on 1st potential flip.  I dont have ideas of what is best towards keeping floor plans or knocking a wall out here or there for best look to quickly sell..  Who is usually to get advise?  Is it my realtor most of the time that will tell me ideas or do most investors have a interior designer part of their team (and pay extra out of the pocket until iv learned the potential ideas. Does any remodeling companies give their opinions when bidding possibly or is it mainly up to me camparing to comps.        Please and thank you in advance for any advise.
