Hello! I'm an architect and I can have this job done in 1 week.
I have the basic computer knowledge you're asking for and have the training required to supervise and carry out the whole interior design (furniture installation, electricity, plumbing, and others).
I'm not exactly located in Caracas, but I can travel there and stay during the required time.
You can contact me through the chatbox to set up all the details about this job.
