We did our deck about 5 years ago and couldn't find anyone who worked with Ipe. It is very labor intensive. My DH ended up doing it himself, and it was hard work. Expect to pay $$$$ for labor in addition to the cost of the Ipe. And make sure you read up on the install options and understand the issues than can arise if its not done properly.

It sure is beautiful wood, but hard to maintain the original look. You need to stain it to keep the color and the stains tend to attract mildew,
