Hi guys, need help to gauge the price of some renovation for a 2 storey terrace. How much does these items normally cost?

First time do reno so not very experienced...takut nanti kena potong 

1. Seal existing door and hack the wall beside to build a new door (basically change door location)
2. Hack 2 walls - 100 sqft each
3. Paint whole house
4. Change current plaster ceiling to a fully covered plaster ceiling (new lighting I guess?)
5. Renovate masterbedroom's toilet by changing a new basin, relocate the toilet bowl and bathing area (add a glass)
6. Built in wardrobe (10 x 6ft)
