Conditions & Fundamentals of Hajj and Umrah

Performing tamaatu hajj if umrah was done in the months of hajj

Q: I have performed Umrah recently on 13 Zul Qadah. Reason was that I had to stay in Jeddah and leave for HAJJ on 7 zul hajj from Jeddah. I was told to perform umrah then go to jeddah as I was coming from taif. Now, can I perform niyyah of ifrad or tamattu?

If I perform Ifrad, must I do qurbaani? If so, will it be considered as wajib or sunnah?

I am staying in Jeddah for 3 weeks but my desire is to perform Ifrad hajj as in Ifrad it's sunnah and person of Ifrad is free to go for tawaf ziyaarah after rami and qasr. I prefer Ifrad but umrah in shawwal & zulqadah am I obliged for tamattu or niyyah counts?
