Here is how I saved one of my customers $40K


A client who recently moved to Spain came to me with with a dilemma. His contractor had quoted him 38K Euros for the Hot Tub that he wanted. Lost in translation, Ray thought this was just astronomical and he was not wrong. Looking around the web, he found me. He dropped me a line, I arranged an initial call to establish his requirements.

Ray contracted me to design and supply the parts needed for his Hot Tub. In keeping with the DIY nature of our site, he did all the plumbing assembly himself.

It came in at around 5K for the parts, and as I provided him with the designs and methodology, saved him thousands in the process.

Let me do the same for you!
