Leasing office furniture, computers, printers, etc

Does Bangkok have good options of this nature? We might, and I do mean, might, be looking at a 6-9 month space and no doubt it will be bare. We would need to kit it out with furniture, equipment, phones, internet access, etc.

Am I just dreaming about getting this done without pulling my hair out?

Executive offices aren't really an option, as we need to be able to have instant access to meeting rooms, so not sure how else to look at this.
