possible solution found...

I have a solution. It is not ideal but it keeps me going. The keyword is virtual office. Basically you pay an office company so that they will put your name on the mail box. These companies do a bit more too. Usually they offer shared offices and actually receive post for you and even forward it to your address. Depending on the monthly price the services are endless. I found a few in Berlin. One of them is actually just 20min away from my home. I've asked them for a pricing as they did not have an offer on the website. From the other companies I gathered that it will cost me about 120euro a month. Holy bimbam! With this extra cost my liquidity will be next to nought by February next year unless my shirts sell successfully.
