Where can I buy Saas marketing analytics web and dashboard admin theme/template

Hi fellow indiehackers,

I have a very small idea that's pure play Saas marketing startup that I would like build and would appreciate any suggestions.

Brief background, I am NOT a programmer/web developer (I have digital marketing background) therefore building my idea from scratch is not feasible as I do not have the technical skills nor the fund to outsource idea to a Saas developer. For the past few months I have been browsing through template after template all over the places. However, I have not come across anything meets my current requirement.

My Q: Do you know any site that sells a clean functional template that has dashboard admin (login) for the customer. There are really nice HTML landing page that are really beautiful in terms of design, but they are merely a landing page and cannot function as a functioning website that my clients can login.

If not, is landing page enough as an MVP and how do I go about building the site? I thank you in advance for your time and apologise as scribble this post whilst on a train. Cheers
