Help to highlight the weak points of the website design. Need advice

We are seeking for the fair and objective recommendations on how to change or improve the design of the website. Our project is aimed at connecting the clients with the direct financial service providers. The website actually operates since 2013 and the design has been improved a couple of times.

We have already conducted the usability tests and the results were rather satisfying, but the conversions are still lower than expected. So, we think that there may be a design issue that prevents the customers from using the service.

We would appreciate any recommendations as well as viewpoints to help us improve the website interface, usability, design, etc. The website is located at https://personalmoneyservice.com/

Thanks
