Hi,
I need to buy btc or eth using following payment types:
-international wire transfer
-debit card
-western union
-paypal
about 1000$ in value, thank you.
For Eth you can try any altcoin exchange to get the altcoin like ETH, LTC or Dash to get the good value. Don't go with the trading site because price will definitely prefers huge amount. For bitcoin you can find the people here in this section itself according your payment options and you can get the bitcoins in exchange for fiat currency in Localbitcoins.com to buy things in any location.
