First, I would be looking at WHY it slopes - is this an indication of a foundation or subfloor support issue ? (Which could be a minor or a major cost issue to remedy.)


For minor sloping - say maybe up to an inch or so out of level, Flooring contractors commonly do this before installing the flooring - using pourable self-levelling compounds (exact type depends on subfloor material and what is going over it). Commonly around $0.25-1.00/SF for that repair. For a pieced or plank tile or stone floor the additional cost might be negligable - just more thickness in areas of the mud coat, if using a mud coat under it.


Otherwise, for a house which had settlement issues overall usually the entire house would be jacked to level and shimmed at the junction of the foundation and the rim joists (wich proper grouting of the resulting gap). Commonly in the few or a good couple of thousands of $ range. Some FOundation Repair contractors do this, as do some House Moving companies.


If only one room has a problem because of really poor construction initially, or because it was tilted due to rot or termite damage which was fixed but not properly levelled, then you could take up the subfloor, put in custom cut shim pieces on top of the floor joists, and put subflooring back down (possibly even the same subflooring depending on how easy it came up). Carpenter - Framing would be the normal person for this type of repair - or even a Handyman who is a good carpenter and pays attention to the leveling operation, using a laser level. Might run (VERY rough ballpark) on the order of $3-5/SF unless glued down or needing to take out the subflooring in under the walls too - here is a link to a recent similar question on replacing subflooring:
