I don't think you have posted in the wrong place. 拜 = pay respect, "respect" as in the act of worship. 托 = thanks, not "supporting with he palm of the hand" nor "to entrust", "entrusted with". The closest equivalent using a single English word is "appreciative".

我觉得你要找的词无非就是please! come on! kindly 之类的，拜托其实也有几层意思，看具体场合选择合适的词汇吧。试举几例， Oh come on, don't lie! 拜托，别撒谎了！ Oh, please. Do shut up! 拜托，把嘴闭上！ Kindly stop kicking the back of my airplane seat！拜托不要再踢我椅子了！ 你赶脚咋样？

You are welcome ~ Actually 拜托了 is also kinda fancy. There might be two occasions for it to be used. First, it's for something really really important. Second, a girl trying to look cute so that others might say yes to her request.
