I think riddle ra mno ko suggestion is very good too..... 

@mno : tara land rent garera bamboo plantation garna would the land-owner agree??? Nepal ma jagga bhada ma dinasath je pani garna didainan ni jaggadhani haru le..... other than that I like your idea....

@riddle : tyo restaurant business saturate bhaisakeko chana ni haina ra.... if there is something innovative and a new idea is catered to quench the thirst of "Its something different, lets try it " wala feeling then it will work I guess..... I like your second idea a lot... of recycling tara yaha pani government subsidi pauna alik garo cha re achel.... I was looking at a palstic recycle small company in kathmandu's report and they were making decent amount....

Nice ideas....
