btiana520 , we do not fix devices here at ifixit, I will post links below for you to get an idea of replacement screens prices and also links to show how screen is removed for replacement in case you would like to give it a try. You can also do a search for your phones screen assembly to possibly get a lower price, just make sure before you order, part it is the correct one for your device. If not comfortable doing the repair take it into a good computer/cell repair shop and have them give an estimate.
