Live auction website development with crypto integration as payment method

I would like to build an auction website like my website. Like Proxibid.com


I want to make it completely free. All of these auction platforms charge auctioneers too much money. I want to make mine for Another example is
Liveauctioneers.com
Or
Invaluable.com

I want to build this as quickly as possible. Please quote the project and tell me how long this will take

Online auction website, please see example websites I sent you.


Please let me know cost and timeframe

I want centralized for the new project

I want the functionality to be exactly as Proxibid.com

I want to offer the website to auctioneers for free because these companies charge way too much money

I want you to design everything

You know my goal. I want to make it a free tool, same kind of layout as liveauctioneers.com

Same functionality

I need to make it where each auctioneer can load their own auctions and do not share client/bidder data unless they opt-in to do so.

Each auction house is very protective over their bidder lists because that is what makes every auction business valuable

I want it to be built the best

I want to be able to handle 5 million site visits per month

We must be able to support that kind of traffic
