you cant apply for visa with an expired passport, you cant renew your expired passport without cfo seminar... in short you have to do the seminar first then renew and amend your passport and then you apply for visa. you can do cfo seminar in cebu as its near davao. if you have friend/relative there maybe you can stay with them for a day or 2 for the seminar for you to save a bit. good luck.
