Charity club night

Hi my name is danielle Mckinnon and i am going to ride a horse across Mongoila next year to raise money for charity . I am holding a club night on the 28th of November and am looking for some help designing my flyers . I have a design and everything in mind just have no idea how to put it on the computer . I am looking to do it for no cost but would provide free advertising please email me on dmc85:hotmail.co.uk if you are interested or have any ideas.
