Restoration of a carved golden console table. I

Hello,
Today I started my new restoration project for Uno Langmann Limited Fine Art, a very prestigious antique dealer on south Granville in Vancouver.
The piece is a console table. A console table is a table fixed to a wall with its top supported by consoles or front legs, in this case the console has only one leg. 
The console table is carved and gilded wood possibly Italian and 200 years old.      
The piece has several serious problems:
The main problems are the flaking of the gesso, and missing areas of gilding.
The gold leaf is missing, which is caused by improper cleaning of the gilding over time. The gilding and gesso are in such bad condition that in some areas you can see the wood.
