Conditions for Jumuah Salaah

Q: The masjid in our area is fairly new. We have, for Jumu'ah, about just over a dozen musallis. It is a mixed congregation of Shaafi and Hanafi. Our imaam for Salaah passed away in September. Since then, while we are looking into appointing a new Imaam, we have invited other Ulama to conduct Jumuah. 

The last imam who came, informed us that our Jumuah is problematic as per Imam Shaafi, there should be at least 40 men. 

Is it correct? Or can we continue with Jumuah Salaah?

Q: In Jumu'ah prayer in our mosque, the main gate is open and anyone can come in. However, the indoor hall of the mosque, its doors are closed, but not locked, and anyone can come in if he wants to. So is our Jumu'ah prayer valid?

Q: My work includes a lot of site work, where in some cases may be in rural areas where there are no masjids present. Regarding this, in a case where I have to be on that site for multiple weeks, is it allowed to miss Jumuah and read the normal Zuhr Salaah for this reason.
