Technical help with MAC/ PC/ handphones

I am looking for someone (based in Singapore) who is good with laptops and computers (both Mac and PC), phones and identifying random cables and power plugs to help me sort through my 10 years of "tech" stuff in my house - and basically transfer the data if any, somewhere else online e.g. iCloud or Dropbox, and then wipe and destroy all my old devices. This is not an easy task as there are tonnes of cables and I don't know what goes with what and some of my old phones (e.g. a blackberry) - I have no idea where the cables are. It will be helpful if you have some personal "master" cable. The devices I have are: - a very old Mac - a very old MacBook - 3 old windows laptops (I think Toshiba, Asus and one more can't remember brand) - about 5-6 old handphones And all of the above - needs to be data transferred, data wiped and then I will send them to digital recycling. As you will be dealing with my personal data, which although is probably not very interesting, I will require you to sign a Non Disclosure Agreement (NDA) to not to disclose anything you see or there will be legal penalty for the breach. Also - you cannot be afraid of dogs as I have 2 dogs in my home.
