I want to mod my IBM 5160

I am looking for a skilled professional who can help me modify my IBM 5160. I am interested in making specific modifications such:
1.Install SD or Compact flash memory card reader through an additional ISA card. (Must coexist with my hard drive)
2. Install a Network card. Must be able to connect to the Internet through an RJ-45 cable connection.
3. Install a vintage PS2 Mouse
4. Install a vintage IBM Joystick. This joystick has the connection port with the IBM PCJr but not with the IBM 5160, we must find a way to connect it.
