Well, awesome to know that you are considering a startup. Wish you all the luck.
I don't have a link or wiki that details all the steps for you. I think there should be one. If we search around and don't find such a resource, we can always set it up as techies and make sure to curate our collective knowledge there. It will be useful to many.
However I can think of a few "programs" or people helping start-ups now in Lebanon and they could be of help to you.
For example I know that
http://www.altcity.me/ has
http://www.bootcamp-lb.com/ - it might be interesting if you enroll in one of their upcoming bootcamps and they help you think through a lot of things, provide you some space, mentorship.
I know there is Bader, Berytech, Wamda, UK Lebanon Tech Hub , Arabnet, BDL Accelerate, Beirut Digital District, TechWadi and a few others. I know this is just a list of keywords, but it might be helpful if you google them around and see if anyone doing anything helpful to you.
I can recommend someone to talk to via DM (he can help you with the financial planning and strategy side) - also, let me know if you want to talk to techies who already did their tech startups. I also have a few names in mind.
I am asking for you to DM me, so we can exchange emails and real names (even tho I think I know you) - it used to be cool to introduce people by their nicknames, like hey this automata... but I think now it scares people ;p
Again, good luck figuring this out!
