Mine ess, and use it to get your runecrafting to 44 so you can make natures. Mine iron and coal, make them into bars, make the bars into steel plates, then make natures and alch the plates. Fish lobsters for money and exp. Your choice if you want to cook them or not. I think raws are worth more, but who doesn't like cooking exp? Cut maples or willows, make them into bows [without strings] until level 70 fletching so you can make yew longs. Cut yews, make into longbows (u), pick flax, spin it, use the shafts on the strings, make natures, alch the bows. Also you could train combat with slayer so you have access to better omnsters to kill. I've used pretty much none of those, but they seem like good options to get you off the ground, as well as giving you some decent exp in a variety of skills.
