Overcoming complex MVP development. Suggestions?

I've been working on a Ad Tech Solution project for a the past two months. I have a background in digital marketing so I came up with a SaaS solution to solve fraud and transparency issues in the industry.

I love the lean start up methodology so I started plotting out my plan and identifying the biggest problems to solve first. In my case it's the MVP since I need a digital platform to gather customer feedback and gain traction and confirm product/market fit.

The challenge that I've run into is that in sourcing devs/white label solutions for the project, none seem to meet my requirements or are too expensive at this stage. I want to avoid developing the software myself if I can and have been told that I need a CTO or technical specialist to help, the following issue with that is that I haven't been able to find anyone in my sphere who would be as invested in solving the problem as I am. Not wanting to remain static however I'm looking at ways that I could perhaps start with a manual process and/or begin exploring component building the project.

I'm still as excited about the project as when I started so definitely don't want to lose the momentum. Looking forward to sharing updates and hearing any and all suggestions!
