Help re design and build on my website in Wordpress

I have an existing website I've just got off the ground but I'm not really happy with it. The business is a new startup and I need the website to be investor pitch ready. It currently has stripe integration etc but there's no apparent back end to it when registering and I've lost a bit of faith in the people who got it to where it is now. I need someone who understands what I am doing with the business and then to possibly re design a lot of it. It's not huge at all at the moment and doesn't need to be but I need to make some things more headline with it and for it to stand out way more than it does. Happy to replace logo/design anything really. Layout wise it works ok but graphics/functions etc will need some work and the stock images are not what i want in it. Once I've got it to a stage where it's investor ready etc I'd be looking to engage again to continue building on it, adding more content into it and helping with back end functions / ecommerce side etc so this would be continuing work going forward for the right person. I have left the auto setting here on budget but please note I am flexible on this as I appreciate we need to talk through things first and for anyone to see what is currently there and access back end etc.
