What resources/budget do you have to throw at this? Do you want to DIY this and find a VA/appointment-setter where you define and control the process for long-term benefit? Or are you low on time and need someone who has existing connections like an M&A broker? Think you need to define the "what" in terms of strategy before you can properly answer the "who".

credibility:
- have built outreach/appointment-setting campaigns for 26+ different B2B industries.
- know a bunch of brokers that are in the bootstrapped world. they have a lot of relationships with investment firms.

non-credibility: don't know anyone in VC space in personally. Can find you that person though.
