RFE- Do i need to appoint lawyer now?

[Avia 7]

I received RFE.

I need help please. Do i need to appoint lawyer now or i should wait for uscis to interview me and then instruct lawyer?

i sent all the evidences i could. I filed waiver with spouse death but we didnt spend much time together and he passed away less than 1 year together. 

We didnot have any children. I was housewife so we had separate account which he made for me to spend. We dont have any lease deeds or mortage in both names. The only thing i can send is the 2015 tax documents to show that we filed as married filing jointly though he passed away in middle of 2015. I sent photos, 2014 tax and affidavit by 3 people. They ask for affidavits too now i dont know who to ask for more affidavits. I sent 1 affidavit from my friend, 1 husbands friend and 1 his sister. I will maybe ask my cousin sister from another state to do an affidavit for me, she met my husband and me when we were together. I have since moved to different state.

Do you think they will call me for interview since  i will be sending only my 2015 tax document and 1 affidavit and few letters addressed to me at my husbands address since we were living together and one letter to them giving explainations in response to RFE? or should i appoint some lawyer before i respond to the rfe? Please advise me.
