Monthly income with bonds

hello

My question addresses to experimented bonds traders, I have almost zero experience with bond trading.

Assuming you want to have a bond portfolio of 6 bonds (each paying coupon twice a year) to generate a monthly income.

Here are my questions:
1- The bonds are US-Treasury bonds, which ones would you use? (please provide the isin of the bond)
2- Would you use non-US-Treasury bonds for the same aim? Why?(please provide the isin of the bond)
3- Can you achieve a monthly income with e.g. just one bond (you can take here *any* bond)? Which one would you use? (please provide the isin of the bond)

Thanks
