Some commission standards for tabletop:
http://www.centerpieceminiatures.com/commission-work/#shq
All Miniatures are base coated and painted with one highlights and one shadows (subject to change depending on the effectiveness of the colour theme). All details of the miniature are painted.
If relevant, supplied transfers are applied (such as army badges or Space Marine logos).
Basing of the miniatures is to your specifications (colours and texture) with the limits that up to two differing items will be put down e.g.: brown sand and grass flock. Basing also includes movement trays.

Tabletop is my cheaper standard. Models painted to this quality will make very very attractive units, or eye catching heroes. Tabletop in general is around 3 layers highlighting, and 1 ink wash, with a very neat finish. Models painted to this standard will look fantastic while gaming, but are also affordable.

•Level 2 paint jobs are our most popular painting level. We refer to this as our “Table-Top” quality painting and the model will have a clean base-coat which is often airbrushed, low lights, 1-2 levels of highlighting per base color, and detail work such as eyes, etc. These models look excellent up close and on the Table-Top.
Well, as shown, rather subjective.
So starting at "block painting" just getting a base color in the right spots: paint by numbers may be enough for some.
Apply shading washes: gets some 3d to it or the "dip method" many finish here.
Edge highlighting to get some "pop" back to the miniature: right here is about where tabletop stops for me.
