Do you have experience with connecting to marketplaces?

Hi! I want to connect my site with marketplaces, which offers affiliates programs e.g. Amazon (I know about commision cuted), Aliexpress and others. On my domain sellema.com I will have wordpress theme with possibility to connecting many marketplaces like above.

Is there anybody who could help with it? Write here or on: hello@sellema.com

Thanks :)
