I should imagine most tillers on this site could trim doors, plinths, remove toilets, basins etc, and would do it in there own homes, however when doing it for a customer then that's a different kettle of fish, first off are you insured to undertake such work, if you remove a toilet and it leaks afterwords, it will be you they will be ringing to sort it and repaire any damage, I once plained a door off for a customer and all I got was grieve apparently the 4mm gap caused a force ten hurricane to come under the door, inside kitchen door as well, not even an outside door, and she insisted I paid for a new door, since then I stick to tiling.....its a lot less hassle.
