Generally, the company putting down the sod would fill low spots and grade and compact that, amend the surface with topsoil as needed, place topsoil for the sod bed, then place the sod - all in one price.

If you are levelling and prepping the area for sodding by yourself (a pretty good sized job for this size area), generally you do not want more than about 1-2 inches more topsoil in any area than in others or you will have soft boggy areas, so using topsoil to fill low spots of any depth is generally a bad idea.

So, to level out low spots you need to fill with a structural fill or sandy gravel that compacts well (usually using a plate compactor to approximately the density of the natural soil there) - generally a driveway "base" material (which normally is used right below the paving) and has about a 1/2-3/4" maximum particle size is used for this. Then topsoil 1-2 inches thick over that and blend it in so there is not a distinct drainage boundary between topsoil and subsoil. Then typically 2 inches more topsoil (up to 4 inches in cases where underlying soil will not support root growth like in clean gravel, sand, or shallow bedrock or glacial debris areas) to provide the growth layer for the sod roots to extend into - with fertilizer and soil amendments as necessary for your area.

In general, for the best sod growth, unless you natural soil is quite loose and the area has not been packed down by being driven on, it is best to plow/scarify the existing ground to about 6 inches in depth to provide a good loose material for the roots to penetrate and for water to drain into. Of course, if you have trees or other spreading rooted plants like shrubs you cannot do this without tearing them out, so core plugging is advised if the natural soil is not rocky. However, most lawn companies skip this step and commonly get acceptabel results, though the lawn will be more sensitive to drought without that measure.

Here is a link to a short article on the general DIY procedure -

For the fill, an Excavation or Landscaping contractor if you want it both delivered and spread/compacted. For the material only, Mulch and Topsoil for the topsoil (be sure you are getting a suitable material for sod bedding in your area - ask sod company for recommended sources), Stone and Gravel for general levelling fill. In most cases, either type of company will be willing to supply both types of material, though some stone/gravel companies will not topsoil because it is a pain to clean out the truck bed afterwards so it does not contaminate structural fill which they might be hauling next.
