Sure there are people that have the ability and patience to do their own repairs, if so I haven't met them. 

I have met the people that have bought DIY "Do It Yourself" repair kits and got in over their heads.  Quickly they realized they required help and phoned me. Like you, I have seen those kits on the internet.  And like the people that have phoned, I believe the kits are a huge waste of your money.  The tools are inadequate.  The seaming tape is double-sided tape that usually doesn't hold past the first five minutes, let alone any length of time after that.  Are the people that sell these kits interested in helping you?  Or are these kits just a get rich quick scheme?  You decide.  My opinion is as follows . . .

Please don't waste your time and hard-earned money.  Even if you don't call the number below, phone someone that does know how to do this properly.  This will not only save your money and time, it will save your sanity
