i also agree with TS.
It's 1 thing to draw beautifully, but entirely another when it comes to detailing. In this field without detail drawings, you will encounter many problems on site if just based on 3D drawings to construct. And RM18k for 3D and furniture layout is quite high end, good for him but i did a project in Parkcity b4, owner paid designer RM25k for 3D drawings without any detail drawings. End up the whole idea can't be use because on site measurement differs with 3D drawings and most of the initial conceptual design differs completely. It's easier to design shoplots because there aren't many build in furniture, but for residential mainly bungalow units where there are many build in furniture, without detailing, you wont end up with a nice interior.
