Don't try putting too much on your flyer. You could spend alot on them and in reality most will go straight in the recycling bin. Put your business name, services provided,contact details, website if you have one and maybe a few photos. I don't believe in creating all singing dancing flyers, just for them to ne binned
When I did my training I was told the first time you flyer an area, 90% of them will gp straight in the bin, The remaining 10% some will be put in a drawer" for future reference" and some will act straight away and call you.
