I am either debating tackling this myself or with somebody or paying a shop to install them. Any recommendations?

Harbor Freight is your friendI am in San Diego and would probably be more available on Saturday since Sunday is Easter. I would probably dive into myself but I don't have jackstands etc. and would rather to have a helping hand around that knows what they are doing. Well if anybody would like to help out on Saturday I can either meet at your place or have stuff brought to my house either or. I have some tools but no jack stands, floor jack, or heavy stuff like that.
