Hello, I can help you to do this job. I'm an Indonesian, so I can understand the explanations there.
I've calculated that you should set about 166 USD, 33.25 USD is the price of the item, 34.00 USD is the cost of sending to Poland (this cost calculation is still be rough, because I don't know how much is weight of the item you'll buy), and the rest of that is for another unpredictable expenses and my commission,
Feel free to contact me first if you're interested with my bid, so I can explain to you the details. Thanks.
