Hi
Seriously though in no particular order
1) Photo of yourself, people like to know who there dealing with.
2) List of Benefits, why people should use you.
3) Headline, containing your USP ( unique selling proposition ).
4) Your address, if you want local work.
5) Dated special offer, whatever you are happy offering.
6) 0800 Number, personally i would only use this if wanting work more than 2-3 mils from where you live.
7) Money Back Gurantee, Making it risk free or the customer.
Cant think of any more.
