E normal sa ceri ajutor daca simti ca nu te descurci. Dar mi se pare mie sau ceri proiectul in intregime?Pt. 723 poti cauta pe google, caci vei gasi o gramada de aplicatii, dar nu cere sa-ti faca cineva proiectul decat daca esti dispus sa platesti.Aici ajutam pe cei care au nevoie, dar la pomul laudat nu te duci cu sacul.
