Are there any successful examples of a marketplace where performers share commission for clients?

Question

Business Informatics

Let's say Vasya has a small construction and repair company, and Vasya has been sitting without orders for a year, sucking his paw.
And Vasya decides that the situation without clients is already so desperate that he is ready to share 50% of the net income from the order with those who bring him a client with whom they will do the project.
On the other hand, there is Kolya, who is too lazy to work, but wants money. Kolya has a very wealthy school friend Eduard, who yesterday told Kolya over a beer that it would be nice to build a high-quality gazebo with a barbecue in the country so that it would be comfortable to gather with friends and spend time there at any time of the year.
Kolya goes to a well-known site, where there are a lot of performers who are ready to share the commissionfrom order. Here is the listing: “I am building a house - 15% of your earnings; I make a website - I give 45% for a client's referral. Kolya leafs through it or searches for an offer for the construction of gazebos - from Vasya. And he recommends Vasya to his school friend Eduard.
E. and V. agree, the work is done. Eduard gets a gazebo at a price that suits him. Vasya gets a job. Kolya gets his share from the commission. Service is yours. Everyone wins. Taxes go into the country's economy. The economy is growing.
Those. a certain service that acts as a catalyst for transactions at the expense of a shared commission. An opportunity to earn by undertaking to find a client for services.
Are there any international / local promoted projects of this kind?

Answer 1

It seems to me that there is some contradiction in

international / local promoted projects

and

Kolya goes to a large site, where there are a lot of performers who are ready to share a commission from an order. Scrolls through it, or search finds an offer from Vasya.

For then Kolya falls out of the chain at the stage "the oligarch enters the promoted service", otherwise he is not promoted at all.
PS: All the problems of such services - no one can guarantee anything to anyone, because if Vasya messes up, as a result, Kolya will get a hat, as a person who recommended Vasya (consider vouching) and also received a percentage. And it will pay a penalty of 200% for a 2% commission.

Answer 2

I saw such a service, there is a directory of organizations and a bulletin board, postopam.ru

Answer 3

In the USA there is https://www.thumbtack.com/ there, and it seems that there are also performers for repairs,
Marketplaces do not necessarily take% of the transaction, someone sells lead contacts (thumbtack seems to work this way, but I'm not sure), the same Avito is also a marketplace - only they monetize more through advertising and paid services
