Not from personal experience but from a lot of research, the places that seem to be cheap and do a decent job are poland (NOA clinic, a few not so positive reviews on here lately but also a lot of great ones previously), czech republic, india (probably the cheapest but quality can be difficult to gage, by the pics you can get great results for $600-$1000).
Korea seems to be really good and cheap
http://allthatbreast.co.kr browse the korean language site on a desktop with google translate they have a ton of cases explained but needs some digging to navigate the site.
You say you have a mild case but require skin removal? That seems contradictory, skin removal will probably raise the price in all these places but not much. Also skin removal probably means more scarring and you should be very clear about what type of technique is going to be used beforehand to avoid disapointment.
Wherever you go it is best that you plan to stay for a while so that you can have contact with the doc for at least a week or 2.
