This should probably be moved to a different forum but beyond that....
multiple solutions are available to you:
1.submerge your boil kettle in an ice bath while chilling with wort chiller
2. get a pre-chiller which is essentially another wort chiller that you put in an ice batch so that the water entering your wort chiller is cold enough to get your wort down to pitching temps.
3. get a pond pump and just re-circulate the wort chiller water in an ice bath once you get the wort temp down to your water temp of 80*.
4. do all 4 of these if just get really excited.
