structural plie design and structural precast concrete design

I am looking for an experienced professional to help me design a structure for a residential/commercial purpose. The structure must have a medium load capacity and must be completed within three to twelve months. I need someone with deep knowledge about structural pile design and structural precast concrete design, who can understand the technical complexities of this endeavor and advise me on the best design approach to achieve the desired results within the set timeline. This is a residential construction project for 1400 units which is located in an area with a high water table and on waterfront property. We would like to have all structures on wood piles driven to bedrock about 30 feet down and then have a precast concrete double "T" slab on top of the piles. Conventional wood frame construction can be utilized above this. It is a new resort property in East Texas.
