It is narrated from Sayyiduna Talha bin Ubaidullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade that a townsman should trade on behalf of a villager. This is a lengthy hadith.

It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade meeting traders before they reach the markets and that a townsman should sell goods on behalf of a villager.

Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) forbade meeting the caravans bringing merchandise. If someone buys goods from them, then when those goods are brought to the market, the owner will have the option to take them back.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade meeting caravans (ahead on the way) and that a townsman should sell the goods of a villager. Tawus says: I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) what is meant by a townsman not selling the goods of a villager? He said: It means that he should not act as his broker.
