New exterior front door

Hi, we have external front doors-French open outwards, we would like to have them replaced and open inwards, this I would think entails removing complete frame etc and replacing this also. So if the builder wants to supply and fix-no problem or we buy them based on his recommendation regards to sizing of frame and doors. Dimensions are: 1750mm length x 2x 755mm across this is inside of door frame.
