It's easiest to use an attorney to set everything up. They will do a name search to make sure your chosen name for your business is not taken, and is acceptable to the authorities.
The attorney then does the paperwork naming the 7 shareholders forming the company. (if you are alone, they typically name 6 others in their firm,as you need 7 shareholders to start up, and then at least 2 shareholders to continue as a legal business.) Then the governmental office issues a tax ID number for your business. A public notice is filed in a local newspaper. The attorney then goes to different offices and gets everythng signed off on, and stamped.
Throughout the process, your attorney will pay the necessary fees at each office. The cost of setting up your company will depend on the amount of authorized capital you choose to start the company with, and the attorney can explain this process to you. (this particular fee has the greatest variability in cost, and can greatly affect the cost of setting up your company)
You will receive the paperwork (your articles of incorporation, designation of shareholders and officers, tax ID issuance, a carnet with this number, etc) once they are done, a corporate seal, and undated letters from your appointed shareholders resigning.
I think mine took about 6 weeks or so to get done.
