A comprehensive approach to design and implementation of the plans would benefit you in this case. A team of interior designer, contractor and possibly architect (if walls are moving or there is a more involved construction plan beyond decorating what is there and dealing with functional issues related to the interior design). Sequencing of trades and scheduling is the job of the contractor while providing costs for the implementation of design work. Designing and dreaming up solutions is the job of the architect and interior designer. Using a team approach with egos left at the door will give you a doable design, a solid budget and a reliable schedule. Best of luck with your project!
