Advertising Help Wanted

Hi Ya start ups,
I hope your business is going welll and growing strong.

Today i signed our company up to a website/directory called 118trades.com
i think it's going to be the best bit of advertising
i've paid out for ever they've been advertising on radio and tv and they take refrences for the companies so that they don't list cowboys.

Thing is i've got to write about 150 words on our company and six bullet points.This is where you guys come in, I would like to know what you think of what i have written below and if you have any ideas it would be much appreciated. Id like to keep it as short and informative as possible and light hearted since i belive if i can make people chuckle then they'll remember it ( who said business should be boring and straight faced.)
also i'd like to mention the company name at least three times so it gets into the heads of customers.

In case you don't know we're an electrical contracting company based in Enfield/Romford.
I know you guys are good at tag lines so come on give it a go.

If you live in or near my area i may do some discounted electrical work for you or take you for a drink for the best one(s) that i use.

Also if anyones got advice on advertising i'd love to hear it. What has and hasn't worked for you.

Below is what i've written so far the stuff in brackets are alternative to what i've written. Thanks in advance for any feedback
