I am not an expert but as of my best knowledge, if you can focuss on DB mgmt i am sure you can make atleast 80K a year.I have seen many ppl on this field even the cheaper company (Foxconn) pays 65K for the beginners  for DB mgmt field. But again i am not an expert on this.It field filed has a variety of section you already know that and nepal ma DOC huna lai science padnai parne , Engr huna lai maths linai parne jasto ni haina, be focussed in any one IT field but be a pro.Good luck buddy.
