Leveling farming, capentry, handicrafts etc

The first thing you will need is a farm, an 8x8 will do. The second thing you will need is labor and third is time.

To level farming quick you will need to grow potatoes. Picking them does not give you very many points but combined that with using a blue salt knife you can buy at the general merchant you will gain 5 points toward your farming. The chopped produce can sell anywhere from 10 - 20 gold per 1000 depending on the AH.

To level handicraft fairly quickly without using ten tons of mats, grow roses. The picking of the flowers will give 1 point towards gathering. Using the handicraft kin use the rose to make a flirtatious flower. It will cost you 10 roses and 10 labor but give you 10 points towards handicraft. 

To level carpentry you can find trees growing in the wild so you not necessarily need a farm to grow them. When you saw the logs to make lumber the points will go towards you labor and you can sell the lumber on the AH

To level gathering Grow azalea flowers they seem to take the shortest amount of time to grow of the flowers at 29 min. You can either grind them up to gain points towards you gathering or sell the flowers as they are. Either way you will make some nice gold from it.

To level husbandry raise chickens if you don't have land because you can raise them in a public farm or if you do have land, raise chickens or geese. You can raise other animals but these are cheap to feed and you can sell the eggs or feathers.

 To level leather working raise turkeys or pigs if you want to spend money for the feed. The turkeys are the cheapest to raise and grow in a much shorter time than the pigs. The down side is that they do not produce as much leather and meat like the pigs do.
