請教朽爺，如何培養穆仁智

一直想學朽爺培養一個穆仁智。可是，我著重培養的穆仁智最近讓我很失望。最初認識他是他受雇於一個房子的HOA給我修fence。當時我正發愁南邊離家三十多邁的幾個房子沒人打理，於是跟他聯係。他告訴我他的hourly rate $35/小時。我直接給他漲到$40。之後房客報修我都是直接聯係他，讓他和房客make appointment，修好後發invoice給我，我都是他報多少我就付多少，從不跟他討價還價。希望以仁德之心來感召他，讓他為我死心塌地幹活。以前的charge還算reasonable，最近越來越獅子大張口，漫天要價。最大的問題是謊報工作時間。比如修理disposal花了四個小時要了我$160. 160刀足夠我買個新的disposal （$90) 請人換掉($60)；疏通drainage blockage花了5小時要了$160. 前天，更離譜的是修理toilet leaking花了5個小時，要$210。我買個新的toilet找人換掉也花不了這麽多錢！這樣下去，恐怕不能再找他幹活了。為了能繼續跟他合作下去，我發了個短信，敲打了一下："I am feeling something wrong with your recent invoices. With $210, I could buy a new toilet (about $100) and get it installed (about $80). Can you please correct it and send me a more reasonable one? Thanks". 他馬上回了一個："Sure, no problem. sorry about that".然後給我減了兩小時的labor, 發了一個$130的invoice。其實我知道這個活他隻花了一個小時。因為他到租客家和離開時都給我發了短信，期間間隔不到一小時。我還是給他轉了$130. 然後提醒他說：”the labor time recorded by tenant is much less. Please record labor time more accurately in future”。過了一天，他回答道：“I wasn't charge by hour, I was to charge by the job". 於是我回："I raised your hourly rate from $35 to $40 when you started to work for me a year ago. When did you start to charge me by job, did you tell me and have I agreed on it? Anyway, I need someone to work at hourly rate. If you want to wrk for me at $45/hour, please let me know. Thanks." 他還沒回。我感覺要掰，得尋找新的穆仁智了

 

請問朽爺，您是怎麽培養穆仁智的，按月薪還是hourly rate付的呀？可不可以發一篇尋找培養穆仁智的文章呀？多謝！
