Block Paving Advice

[freakynessless]

Morning all,

I'm after some advice with regards to block paving my driveway.

It's approx 36m2 - this is only my rough measurements and is currently concrete at the moment which looks awful.
I'm getting traders in to quote for the job. I had the first one come round last night, he comes very well recommended on Checkatrade.com and he only lives about a mile down the road. He was a nice enough chap, although very pushy and wanted an order there and then. I explained I'm getting other quotes in and will speak to him later on during the week once I've spoken to the other traders.
From the reviews I've seen, this guys customers seem happy with the work, he has a decent looking website and facebook page, however there's something about him which I'm not 100% sure about. He quoted a price after just looking round the driveway and not even getting a tape measure out! Is this normal? I expected the process to be more calculated than just tapping away at the calculator on his phone for about five seconds.
After some discussion he offered to do the job for £3200, which if my calcs are right and the drive is 36m2 then it's about £89 per square meter. He would be using Marshall Driveline 50's.
Also he mentioned about throwing in the sealing for free, which would normally cost a couple of hundred quid to do. Am I right he's talking about this sort of stuff...

How important is this?

Any advice people can offer would be very much appreciated. I'm just a bit dubious about spending this sort of money and not getting a good job at the end.
Oh, also if it matters we're in Suffolk.

Thanks in advance.

I've asked for first quote in writing which hasn't come through yet.
I've got another guy coming tomorrow morning and another on tuesday so I'll be asking for these in writing too.
The guy coming tomorrow is another local guy who's been established for 29 years so I'm hoping that should be good quality work.

With regards to planning, as long as it drains properly and doesnt spill out on to the pavement it should be okay shouldn't it?

Thanks again

Thanks for the info and advice so far guys.
A quick update on the current position. Trader number two came round on sunday and actually got a tape measure out! I was quite pleased about this. We spent most of our time talking about drainage, which too was pleasing rather than trying to drill me down to giving him an order there and then - although he still hasnt actually given me a price or even an indication yet and its wednesday!
We agreed that as the pavement sits higher than the damp course then the drive would have to slope backwards towards the house and put in a drain in front of the house, this way the guttering from our small porch can also be picked up at the same time.
Initally thinking that a soakaway would be the best best, we then realised that the current drainage (which is currently in the middle of the driveway) leads to sewer anyway so we could just link it up to whatever is already in place.
Trader number three comes round yesterday and was also of the same mindset regarding the drainage.
He gave me some firm wirtten quotes, which was great.
He offered £3,550 for standard pavers (Marshall Driveline 50 type pavers). He said he would also offer the same price for Pattern Imprinted Concrete too which was quite interesting as it's not something we've given much thought to, but we do like the sound of it now it's been offered. My only real concern is that it can be slippery and we currenly have a two year old and a new born too. He did advise they can do it with a non-slip finish - similar to fine sandpaper.
Lastly he offered £3,750 for Chelsea pavers, again, not something we had thought of before but now we quite like the sound of it although there is an extra cost (albeit quite small).

Now to be honest I'm quite bamboozled with all the options, colours and finishes! Although at the moment I do like the sound of pattern imprinted concrete. Has anyone got any fist hand experience of it? And am I right to be concerned about it being slippery?
The guy who offered the PIC also pointed to a house down our road which he did in PIC, which we've always looked and thought it looks great.

Thanks again guys
