Worldwide Parcel delivery to Guinea - Parcels Packages

My sister has asked that I send her a few personal items that I found while shopping here in Los Angeles, California, in the United States. I assume that I need information from a company who participates in worldwide parcel delivery to Guinea. If I have posted in the wrong place, please forgive me and move this post to its correct position.

Does your company have an office or some business location that is near to Los Angeles? If so, then please tell me where yo are located. Since I must package and pad this parcel, I would prefer to be in the presence of any of your experienced employees who can assist me with packaging this correctly. Would you mind doing that for me? Also, how much would this assistance cost me? How soon would this parcel be delivered to Guinea?

Please send me this information to my email address. Thank you.
