Here's what we're in the process of doing (DIY). If I had the plans my DH drew up already on my computer, I'd include them as well. He did a great job drawing up the plans. So instead, I'll just run the figures out for you.
We have a 16 x 32. The deck runs 8' out in front of the pool, 10' out at the end where the pool equipment is (because we'll be installing a slide there and needed the extra space on that end), 5' out along the opposite end, which leads into a 12' area in the back left corner, which will be covered. Then, the backside of the pool, the deck runs 5' out over to the pool equipment.
Now, given all that, we received three quotes: $6500 (labor only), $12K (inclusive) and $14K (inclusive). So we opted for DIY and are enjoying DIY, except for the Texas heat of 100+

Our costs for materials, which includes 5 gal Behr stain/sealant and nice cedar railing all the way around, and of course, a bonus for my DH, a framing nailer (I think that's what it's called): $4500.
We hope to finish installing the frames tomorrow (had a minor glitch today

) and work on getting the planks installed during the week - so we can at least start getting back into the pool again before summer is out. We'll be taking our time on the railing, since we're making it as well, as opposed to buying the pre-fabbed railing.
Hope this gives you an idea of what you're looking for.
