Hi HoaTuoi9x,
Welcome to this forum and to the fab community!
Great that you are preparing a new fablab. There is only one fablab registered so far in Palestine, i.e. Makerspace Nablus, Fab Lab Palestine | FabLabs. And the Institute for Community Partnership (ICP) at Bethlehem University is interested to set-up one. Also in Jordan there are a number of fablabs, like Techworks in Amman and one in Irbid. On fablabs.io you can find all the contact details of all fablabs. I hope you will register your new fablab there soon!
Regarding suppliers, i guess, your neigbour labs best oversee the local options. Further one of the Belgium fab labs is focusing on one-stop-shopping for starting fablabs. They sell relatively cheap versions of all machines as a package. Check: Fab Lab Factory at Home - FabLab Factory.
Which online courses are you looking for? If it is about setting-up and running a fablab, download the fablab-lifecycle report at https://bit.ly/fablablifecycle. It contains the experiences from fablabs from all over the world.
As Andy already recommended: within two weeks the fab community has a week long online conference, hope to meet you there!
All the best
Pieter van der Hijden
