The hose clamp was $0.98 each, I bought two of them (one for the guide and the other to keep the fork in place).

The bike is equipped with disc brakes and internally routed through the fork, I was lazy to remove it. I had someone lend a hand with securing the bike while I used a normal fine hacksaw to cut away. The cut was straight and clean using the clamp, I just added a bevel to the OD and ID with a diamond file.

It took about 5 minutes and overall cost (if I were to buy the saw, clamps, and diamond files) would be below $15.
