Sitting for i'tikaaf in a musalla

Q: May the sunnah i'tikaaf in Ramadhan be held in a facility which accommodates and facilitates the 5 times salaah, including the jumuah salaahs. This is presently a musallah which caters for the residents in the area, over 300 Muslim homes. Consent dues have been granted already for the musallah to continue, alhamdulillah. The nearest masjid is about 4 Kms away which has a limited space for the mu'takifeen. Kindly advise if we could hold the sunnah i'tikaaf for the musallees of the area?

Reciting بسم الله الرحمن الرحيم when continuing to the next surah in Taraweeh Salaah

Q: If someone is leading a congregation, for example Taraweeh. Does the imam need to say بسم الله الرحمن الرحيم after he finishes a surah and decides to continue? For example, if the Imam just finished Surah Baqarah and wants to continue to Al-Imran, does he stop after finishing and continue or does the Imam recite Tasmiyah and then continue to Al-Imran? Please clarify me on this.

Partnership in a business

Q: I have started a new business for which I need some funds. I do not want to take a loan that involves interest. I have found an investor but he wants some kind of profit. I really really need the fund for my business so how do we proceed in a halal manner?
