Jps1006, don't you get to deduct a portion of your home rent/mortgage as a business expense, since you have a room dedicated as an 'office'?
As a one man shop, it would seem that the cost benefits of working out of the home would outweigh the expenses of supporting a seperate office infrastructure.
I agree with Joey D.; First learning to organize and make the most out of where you are would be the best move.
I wouldnt make the leap to supporting a seperate office until the demands of a secretary and employees etc required it.
Just my thoughts. No real useful advice is actually intended or implied.
