Actually my first post was a little incorrect.

Makeover Guys - for rentals

Easyhome - like makeover guys, but for own stay. They have pre-defined templates to choose from for the look of your home. Lots of wallpaper usage, no plaster ceiling if I'm not mistaken, most of the things are chosen by them based on your preferred theme. You do not get to individually choose the exact design of the items. They do allow custom carpentry though.

Groundwork - more akin to the other ID firms out there. You can design from scratch and customise almost everything. Costs more than easyhome of course.
I had quite a lengthy chat with Tessa from easyhome during the MCO. She was very friendly and extremely helpful, feels genuinely like someone who wants to help the client. Props to her. Unfortunately in the end I decided not to proceed because of the limitations above – less customisation and lots of details are left to easyhome to choose for you, without much of your say. They call it a surprise element. But surprises can be good or bad so I decided against it in the end.
