Couple (23) seeking apartment in Amsterdam

My name is Aitor and my girlfriend's name is Maria, we are a couple of 23 and 22 years old, we are passionate about the world of fashion, music and tourism, we are looking for a flat in Amsterdam because we are looking for work in the city, Maria is a fashion designer and I work in CNC machining, we have already lived in Holland for three months in a town near Eindhoven, we have BSN to work, bank account in ING direct and as soon as we settle we will get a Dutch phone number. Our idea is to find a flat for september but if we find one before the beginning of the month we don't mind paying for the part of august. I would like you to contact me to discuss the conditions of the flats in terms of duration and the financial guarantees we have to provide. We also count on the help of our parents as guarantors.
