supplyers for replacing screen

hi i have got another free phone but the screen is completely smashed looks like its been dropped really bad or ran over but reconizes and seems to be working properly other then the screen so no damage to logic board and other parts etc

but i cant find anywhere to buy a new screen + lcd and its the S2 4G version so im not sure if differs from the S2 3g and its not the LTE version its the one with the solid home button and two touch buttons

cheers and preferably the cheapest price possible im just going to use it as a multimedia device (music and testing apps on it)
