You don't have a Petco or Petsmart around? Even then, see if you can't order one off Dr Foster and Smith. You have way too many fish in there for cycling. If you don't have another tank (away from any other fish you have) to put them in and you can't take them back to where you got them then expect a couple to die. I guess you could try doing small water changes every day, I don't know if that will be enough to keep the ammonia down while letting the other bacteria start up with that many fish though.
I think the worst thing is herefishy gave you the advice to put danios in (and not more than 4), you said you would and now here you are with mollies, platies, and danios and unless I'm misunderstanding, you only have 1 danio and 3 platies and I'm assuming since you used mollies in the plural sense then well, that brings you up to at least 6 fish which will lead to New Tank Syndrome and something probably dying off but I hope not and maybe this will be a lesson to you to actually listen to what advice you are given.
