Hi, here's some things to consider:
Firstly, spell check your web site.
How could you get Gauranteed in your header image wrong? Guaranteed!
Secondly, first line of intro paragraph has "with" spelt wrong. If this is a professional business, you need to ensure that ALL communications that are publicly viewable are of a professional pedigree, otherwise it writes off your credibility entirely.
And finally, most importantly - reconsider the wording and terms for your competition. Someone will have a field day with your landline promotion - as you don't even state the conditions of the competition. One would expect that "a free phoneline for a year" would include LOCAL and TOLLS. As you don't disclaim it, they can hold you accountable for it.
Good luck nonetheless!
