on my personal opinion, if have tight budget why nt get a contractor instead of ID... it's alot cheaper.. if u already have in mind the concept u want, go for contractor
i encountered a no of IDs who cannot deliver & yet quote a high px... they ask us of our preference & we told them our idea... turn out the design they created for us is so normal.. i mean if the design is a designer's concept then i think everyone can be a designer
