I'll just put down a few suggestions off the top of my head for F2P scripts I've been thinking of. I plan to start working on at least one of these once exams are over but if you like any of the ideas feel free to use them, just let me know so we don't make redundant scripts 
Yew tree cut and bank, areas below listed in order of preference
-Rimmington yews, with either Port Sarim deposit box banking or Home TP banking (relatively low crowding)
-Falador cabbage patch using cabbage TP and Edgeville Home TP for banking? (moderate crowding)
-Edgeville yews, running to edgeville bank (often crowded)
Furnace bar smelter, using Lumby furnace and bank chest at tutor
-Potentially add crafting as well, gold rings etc. Gold ring profit margin ~50gp/ea if bars are purchased on GE.
Karamja fishing and noting
-Primarily lobsters
-Perhaps swordfish/tuna support
Cooking
-Al Kharid (easiest to script, short distance and no doors/ladders) or Lumby (F2P bank on roof, requires use of ladders but range lowers burned food rate)
-Primarily fish (eg. Lobster)
-Potentially urn support
High Alching
-Relatively easy script, good for profiting/magic training
Long ago, the '90s Nicktoons lived together in harmony. Then, everything changed when the century turned. Only Avatar, the best of the 2000's Nicktoons, could save them. But when the channel needed it most, the show finished. Four years passed and Mike and Bryan created the new Avatar: Legend of Korra. And although the show itself is great, it has a long way to go before it can live up to The Last Airbender. But I believe Korra can save Nickelodeon.
