Really you're not doing yourself any favours ...
If you were putting this in a paper would you just say
Company for sale .. asking price in and around 50k ?
You'd give a lot more details I would assume
Projected earnings ?
Earnings to date ?
Site Traffic ?
Spending 100k on marketing and
PR is great but that money could have been spent on 10 - 20 adverts in the Galway advertiser for all I know
