get a cheap microphone and fake it.
expensive recording mikes will set you back $800.
so get a $10 cheapy and start using things around your house that sound like the audio you want.
scrape two butter knives together while holding them in your fingertips gently for metal on metal sounds.
get a plastic cutlery draw and fill it small stones, then shake it for another effect.
get a music triangle and record that, you can duplicate the sound many times at different pitches to simulate two words clinging and clanging.
make sure the ambient noise is quiet at your house, night time is better.
stay away from the computer if you can to avoid the comps hum in recording etc.
Its what the dobly guys do for movies.
