Build Beautiful Online Business Marketplace/Brokerage (Example Shown)

I would like to build a listing platform that functions the same as & has similar 'good looks' as EmpireFlippers.com. In this, it should be fully functional and as automated as possible given the function of the site above. Here is a basic description of the website: I need a website that allows the listing of online business (in a private marketplace setting) where business owners can get automatic appraisals for their website (via an algorithm on our site) and apply to have it listed on our site (after adding all their site info and getting their identity verified). Our site would gather up all of the information about the site and proceed to post the listing after they sign our exclusive brokerage agreement. In this, the listing page of the site would show descriptions, revenue/profit charts, traffic charts, SWOT analysis, seller interviews, etc. We then can manage the listing (where it is shown on our marketplace) without any URL listed until the listing is unlocked (which is done by buyer verifying their identity and showing proof of funds.). After unlocking, the buyer is able to submit a offer. If accepted, they are prompted company wire information for payment (w/ corresponding form to indicate that they have submitted wire transfer). Then after payment is received by us, we transfer business ownership/information to buyer via site. Then after buyer confirms full receipt, we release funds to seller and ask for feedback. All the while, we would want HubSpot integration to automatically email and track both buyer and owner leads (as they come to us). In addition, we would want part of the website to be focused on listing just domain names – these would not need the complex description as the online businesses – but they would use the same process. Domain owners should be able to get automatic appraisals (via different valuation tool) and apply to list their domains with us. In this, the site should have the following specific features shown in the attached document (most are the same as EmpireFlippers).
