Hi HomeOwners. Recently I have gotten my house and I wanna to do a renovation for my house.
I encountered this ID whom my friend introduce. 
My house theme is Modern and Scandinavia.

 He is quite young and easy going guy who have lots of ideas to convince me. He knows the trend for my new home & I'm pretty convinced by his design. 
Kindly help me check if the quotation he gave me reasonable?. Thank you so much.
