Dear Bilal,
It's Bin Years Em Importing My Vehicles Parts By My Own Medium & Always Material Reach Safe Home But After A specific Time.
Medium = Sea & Air Cargo From UAE To My Home Door Step, Peshawar, Pakistan
Nothing Is Free But In My Medium The Charges R Affordable & Bearable To My Pocket (I save a lot rather then UPS, TCS, DHL etc)
Clearing Custom, Shipping Safe, Taxes etc all is covered ...
If U ll Use Any Cargo Services Like DHL, USPS, TCS etc then From UAE To Pakistan It's Fast Cargo But Will Be Expensive as U Have To Declare The Part Original Papers, Import Papers Etc & When It will Reach Pakistan Then Again U Have To Pay A lot Tax Which Is Calculated By Their Own Way 
& I Don't Take Responsibilities Of Other People Cargo As Anything Goes Wrong Then Other Person Will Make Issue...
In Ur Case U Have Two Options ..
Pay More & Get Ur Work Done Or Pay A Bit Less But Have To Take Chance
