Thanks for the offer but to be honest I will stick to the original firm, I dont see why showing me a facebook page that makes you money should be a problem. Also why have you not got your own if you think its a good idea? Its not just about building a plain page, they brand it and manage it to make sure its visible to as many people as possible to guarantee a result.....
That cool and good luck.
To answer your question:
If I wanted more window cleaning work then I would convert the one I started last year, I dont want to tbh right now I am busy enough, that may change if I can find the right person to drive forward the window cleaning side thats why I had the page secured long before the masses new about it

.
Honestly I do know what a Page on facebook entails I have been studying it amounst other things full times for over a year, it comes down to 1 thing and thats about being viral thats where the money and the traffic is, just what ever you get into with a company, make 110% sure that it is targeted traffic to your page, it is possibel to get 10,000 likes to a page within days, but targeted traffic will convert alot better more is not always better

Hope it works out for you

, sorry never caught your name.
