You can join asiamiles and put your earning to asiamiles. Once you get enough miles/sectors, they may invite you to MPC silver status. However this might only happen after say 35,000 miles or 25 sectors, meaning that you will have wasted 5,000 miles / 5 sectors that could have been put towards gaining Gold status.
If you are sure you want to be a MPC member, you are best to pay the fee.
