[Q] boost to pp moto g topic

first off id like to state that i help run a non profit and we can no longer afford to pay our contract phone bill. we where given several boost mobile moto g's donated to us. but unfortunately boost doesnt have enough coverage for us while where out in the field. id like to flash them over to pageplus.i have a loose understanding of flashing and i was wondering if some one could let me know how to go about doing so. please keep in mind that we are a non profit and dont have the money to pay to flash these phones.
