With the experience u have,puts u in the Regional Airline arena
1000 hrs upwards is the usuall figure.But it rather depends on your definition of WORTH.It depends on whether u wish to come and try your luck here.U might do the conversion and walk right into a job,on the other hand u might not.The door is open,its up to you to decide.Instructing,
yes there are jobs about,charter as well,and regional jobs.There are a lot of pilots competing for there first job here,and i suppose a lot depends on experience.U seem to have what they are looking for in the hrs
dept,but as far as ;IS IT WORTH IT;well only
u can decide if u want to come here,work your nuts off doing the entire ATPL exams,a full 50hr IR course followed by test,a **** load of money ,time,heartache, no guarantee
of a job but u would be in with a shout.The
chioce is yours and good luck.
