You should be able to complete the level 70 class quest with roughly level 65 crafted gear(the kudzu/tigerskin set)... if not even slightly less gear. If you need to make some money before you get the ability to gather the newest mats, then the key is to spend a little time with your servers marketboard. Look at what you can gather now, look at how much it sells for and how often it sells, and find a couple items worth targetting. Then go get them, sell them, and repeat until your cash is in a better place. Some of the good mats will be lower level then you might think. The classic example is Alumen - mined at level 15 but used by leatherworkers until they get up into their 40s(being that this example is used a lot to explain the theory behind which types of mats to look for, on many servers its been over-farmed and the price isnt worth gathering). Some mats have longer shelf life(like alumen), some are used in great quantities(if the whole market sells out twice a day youre on to something), some are inconvenient to get(id rather pay someone then bother), some are only for specialty recipes that sell for a ton(think furniture).

Stella was right, theres more then one way to get scrips from collectables. The weekly custom delivery NPCs pay very well, but Rowena's people are available 24/7 and have no limit. So you want the overly-simple version of starting out on collectables? Ok. Get 600 gp(more is better, this is the absolute minimum as the rotation uses 600 points). That might mean better gear, it might mean melding, it might mean using food when you gather - for now, how you get there isnt important. Your overly-simple(no RNG) rotation is Discerning Eye Methodical Appraisal DE Meth DE Meth gather(1-3 items depending on node, 450% appraised). On a node with extra swings(this uses 4 steps, so without extra swings you get nothing) you could do DE Meth DE Meth Utmost Caution Meth Meth gather(1-2 items at 500% appraised). If this doesnt get you to the minimum to turn something in then you need more perception on your gear. Once youre more comfortable later on you can learn the Impulsive Appraisal version(potentially better returns, involves RNG). Side note: Using all(or even most) of your GP for each node either means downtime or cordial chugging, so plan accordingly.
