That does sound like your spokes or nipples are bad, rather than your rims - but maybe.
It also sounds like your shop is blowing you off - maybe try another who will listen to you.
If you're settled on different wheels, we really don't have enough info to go on, and your budget is a little thin for custom.
300 pounds is not too much weight for the right wheels though - so don't lose hope.
Maybe check eBay and other places and find some examples you can link to so we can help evaluate them for you.
