Anyone know a way i can trademark really cheaply and earn the money to?

not sure on the lagality of this so you would have to check it out firstly put your ideas on paper date them sign them get them witnessed and then pop them or copies in an envelope record the delivery and post it back to yourself but leave it unopened in case you need it at a later date if you make copies you can refer to those, like i said im not sure if this is correct so check it
