I Want Exchange 'Zefiz 1951' Airmail Stamp Exhibition Sc#43 Or Mi#5 For US Stamps

This stamp 'ZEFIZ 1951 airmail' in Scott's catalog has a price of approximately US $175 (Michel's catalog has a price of approximately 220 €)?
I'm asking US $100.
But!
I'm not asking for money to be sent to me. I want to exchange for US postal stamps which I missing.
If someone has a surplus of US stamps (his duplicates) and he wants to exchange this stamp, I'm ready to send a registered letter to him at my expense.
I want to get US postal stamps worth $100 per Scott's catalog.
The Scott's numbers of US Stamps that I miss can be viewed on this link ( http://ic.ims.hr/stamps-that-are-missing.txt ).
I will keep this topic active for 17 days. So, on April 15, 2018 I will close this topic.
Then I will decide to whom I will send this stamp.
I will accept the best offer. If someone wants to exchange, he can contact me with a private message.

I want to be clearer. If someone has duplicate US stamps, he can see the price of a specific stamp from my list in the Scott's catalog.
The total sum should be $100 (exchange 'value' per 'value').
That I would not write a lot text, if someone is not clear what I want, please see the link on this forum https://goscf.com/t/61136.
The customer can decide what his duplicate will offer to me, but they must be from the list on the link above.
I apologize for my bad English.
Best regards to all.
