Based on what you just said, I would NOT try to make a power supply.
Mains electricity can be VERY DANGEROUS, if you do not know what you are doing.
Heck it is DANGEROUS when you do know what you are doing.
And that power supply will be putting out 10 amps of current!

Sorry, but for your safety, my recommendation is for you to NOT make a power supply.
Therefore you have to buy one and have it shipped to you.
