Using FPGA Verilog or NIOS II but only i have 3 month remain. is it possible? Normally to design Simple SD Card Driver how many month?

That's no big challenge. Did you review the SD card interface description? To be compatible with file system, you may allocate a big file with continuous sectors and write the data to it.
