How to Build a Track Record for Fundraising by Offering Advisory and Access in Exchange for Equity?

Hi guys! As I am building my track record to strengthen my ability to fundraise I need advice on offering advisory and access in exchange for equity in the business.... I know a few startups that I could approach but that doesn't mean they would be suitable for the fund as I didn't access their financials etc. How should I move forward to build the track record given the limited time I have to build it before the fundraising?
