7-story building

Hello everyone. I belong to a company in which we are overworked. I have the need on this occasion to make the architecture of a building of 7 floors. This involves floor plans, construction cuts x 2. These will be subject to modification. I have the engineer's plans. I need to know how much it would cost? I will look in detail and analyze each of the profiles, their reviews, the type of work to be done and I will hire and give all the details of the work to be done to the employee of my choice. Do not bid for this if you are an industrial designer or graphic designer, only architects or architectural firms. There are deadlines for the work to be done that must be met. Thank you very much

I was also forgetting, air conditioning and sanitary plans will be made.
