Own business? Cheap advertising opportunity

The time has come again when I'm about ready to get some flyers printed. I say flyers, but they will actually be A6 size ones printed on 300gsm art board (postcard kind of weight). These worked nicely for me last time as they are easy to push through tough bristles on letterboxes without ending up as a scrunched up piece of paper!

I am looking at having 5000 printed. I'm looking for someone that would like their business on the reverse side.

An EXTREMELY low price of £70 and they will be distributed as and when. Some I will push through doors locally, some will be passed to my customers (it's for ink cartridge sales) at car boot sales etc. Obviously at this price I'm not offering any guarantees about how soon they'll be distributed, and due to boot sales etc they could be anywhere within a 25 mile radius so it might be better suited to someone that sells a product via a website and posts goods out.

Alternatively, I'd be prepared to split that cost 50/50 and split the cards 50/50 for distribution how we please.

Get in touch ASAP if interested please as I need to get a printing order in as soon as I can.
Thanks

>>> Here's what will be on my side of the card incase that concerns you...

Ideally a week @RJS

148mm x 105mm @ 300dpi. Keep important detail at least 3mm away from the edges to allow for cropping etc. Ideally PDF but JPEG acceptable. Full colour CMYK process litho printed.

@RJS did you make any decisions about this yet mate? I did PM you but not had a response since. Could do with knowing ASAP as I may otherwise go to print alone.

Thanks

Opportunity still open if there is anyone else interested, but would need artwork in ASAP
