PE Biz Dev v.s. Unpaid IB Internship

hello all,

I graduated undergrad 8 months ago and did a post-grad internship at a boutique valuation firm. Some unfortunate things happened and I left after the 3 month internship. I am now unemployed and am considering these two opportunities:

1. 3 month unpaid IB internship at a no-name boutique (through linkedin research, there are not many past interns who have moved to better banks)
2. a PE BD role for the firm. While speaking with the recruiter, I expressed my interest in moving into a deal facing role after developing sales/BD skills. The recruiter said an internal transfer after a year or two may be possible b/c the firm likes internal promotions or w/e (he may have just been pushing this, but PE Analyst roles at the firm do not require as much IB experience as other PE shops, but I did not get an interview for that role)

If my end goal is a deal facing PE role, am I best taking the internship, then moving to a FT analyst at a diff bank, then PE from there (not easy, given I didnt see any past interns at the bank do this before, and I may have to move to a boutique for FT and then move to a larger bank to gain access to any sort of PE recruiting)

or is the BD role not a bad option? I realize I am early in my career and lack of technical skills could be an issue when interviewing for PE deal facing roles, but I do have 3 months of valuation experience.

Being paid is important to me, but I am willing to struggle for 3 months if its the best long term option. the BD role pays ~50k base w/ total 75k target. Definitely not high pay but ive seen worse for BD roles.
