There are Charters for Fishing, Expedition for Exploring, I am proposing a "Rent a Farmer" type of deal for one of the other main parts of gameplay: our endless need for crops.
One way it could be done is per crop and with the planting/harvesting happening automatically similarly to craftworks; for example if I wanted to plant 2k onions and decided that I didn't want to go back to my farm and harvest/plant again after each increment of growth time between exploring, fishing or crafting, I could pay X gold to have Y batches of seeds/number of crops planted and harvested automatically as they finish growing (similarly as to how craftworks runs in the background as the resources become available), with the crop grow time remaining consistent with perks (I feel changing the grow time would alter the game too much and be too similar to grape juice effects as opposed to just being an added QoL feature).
Alternatively, this could be done through treating planting all crops as a "location" with having different "drop rates" per hour of gold paid for; for example with Peppers having a higher drop rate than Beets. However, this would be limited by the fact that crops are unlocked with farming level, and where Expeditions and Charters are unlocked by access to locations, this would be either difficult to adjust as players gain levels, or limiting to Farming 99.
Similarly as to how expeditions and charters do not drop certain items (runestones, treasure items, gold fish, etc.), I believe that certain crop drops should be limited/not drop for this concept, as where there is the challenge for getting certain crop drops throughout quests, I feel this keeps it in likeness.
Who would this be geared towards? This would benefit any player that is wanting an easy way of getting their desired number of crops without the typical effort of replanting and therefore with a slight increased efficiency. All players have variable levels of gold, so similarly to how Charters/Expeditions are a personal choice based on how much gold one has to spare, this would similarly be geared towards the audience that feel they would benefit from it the most.
