@Interested: in the CBD, you can full office at 10k pm if you search hard enough. Is that affordable?
Secondly, it appears that you want to start a new business that will require internet. If this is the case, do you already have a PC? If yes, just buy your own internet modem from SSCOM or Orange. They are reliable and best of all, you can move around with them.
Finally; ask yourself whether you really need an office at this stage. Who [apart from you] will be visiting it? Clients?
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
