"I quoted a price for the goods" or "I gave a quote for the goods" are two ways of saying this. A word of advice: Unless you want to sound like a spoilt toddler, don't write 'wanna'. Despite all you may have been led to believe, 'wanna' 'gonna' and suchlike are NOT casual, informal English. All they do is make the writer sound childish, rude, lazy or uneducated. If you want to give that impression, that's fine. But if you want to be taken seriously, as an intelligent adult, please just use normal English. 'Want to' is not formal - it's is just everyday, normal English. I hope that helps.

It depends on the context, but most likely you would say, "I made an offer on the goods," or "I offered a quote on the goods."
