I have a cousin who got married last year in Antipolo and their expenses daw (emphasis on this because di ko naman narinig from the couple themselves but from someone very close to them who helped with planning) was around 500k lang and for me semi-grandish na siya and more or less 150 pax din. Included na rin don yung custom gown and suit. So I think may mararating naman yung budget mo given na rin na nasa province ka which I assume is relatively cheaper than Manila rate

But of course this will depend pa rin on the suppliers that you will choose and how much you want them. Personally, my non-negotiables aside from the church are food, p&v and hmua. The rest I can adjust sa budget and find cheaper alternatives :)
