(Hopefully constructive) feedback:
1.) Why only four currencies? Now I can't use it. Netflix has helped normalize credit card usage all across the world, so your potential market is huge, but you've only targeted four countries. I don't get that.
2.) All price/currency fields have placeholders in the format 0.00. When I click on one of these fields, I expect it to go blank so that I can enter my own price. So I just click anywhere on that field and start typing. If I happen to have clicked after the decimal point, and try to type in 2000 (meaning $2000), the value I end up with is "0.200". This is unexpected behaviour for a form field, at least for me.
3.) In your quote entry form, you need to widen the tax % field. When I enter 0.09, the 9 is half cut off.
