Hello welcome to the forum 
Yes the postage rate can be high for international customers but they can no longer use the USPS because of reliability issues and the heightened security on shipping liquids on commercial airlines. So DHL is the only option at this time.
I think you should try a variaty of to_go’s to get a feel for what works best for you. AMMO, Ishine, IH , IO and IG are good to start with.
