What are creative ways to pivot or find partners/co-founders for a viable bootstrapped business that, due to outside factors, is in decline?

So, I have an online, digital product based business. The business went through a difficult troll lawsuit that set it back quite a bit. Trying to recover from this situation has been.. well.. difficult. The funds needed to do the proper marketing and advertising have not been there. In the meantime, while trying various low-cost pivots, most of which have not worked, debts have risen. The business has slowly declined, but IMHO that is largely due to the lack of funding for consistent marketing/advertising. We have gotten by the last few years with barely any marketing and advertising and the things we have done have primarily been inexpensive to free methods like blogs, etc. There is inherent value in this business in the customer base, content, products, user-base, etc. It's getting to the point where I need to do something. I have watched similar companies go through VC rounds and buyouts who did not go through the same troll suit we did. Investors seem unlikely (I would think) just because we have been in decline. I was thinking that possibly we could locate someone who understands our space and therefore can understand our value who could possibly just come on and assume part of the company for a percentage. Or, maybe we could find another business in our same marketplace who already has a team in place who would want to come alongside us for a percentage of the company who could put in maybe some money, but also the sweat equity to do the marketing and advertising needed. I am looking for creative ideas or input from others who have been in similar situations and how they were able to revive their valuable business that 'appeared' un-valuable solely based on balance sheets. I am open to any numbers of creative and out-of-the box ideas. Thanks!
