Good evening! We are a Spanish company dedicated to custom programming for any kind of websites, from personal blogs to totally made from scratch web applications. We have had the chance to work recently in a Bitcoin exchange platform, so we have experience with Bitcoin payments and management; we have also plenty of experience in web languages and NodeJS, which would be the platform we would use to develop your website. We would need two to three weeks, more or less, and we could have a totally functional BalloonBit-like website, running 24/7 totally automatic, without the need of management. Thanks for reading, and don't doubt in asking us anything! - KATcode team
