If you can't craft or do 3 mans you are a bit stuck but not all is lost. Crafted armour will do you nicely if you don't want to do tier 2 stuff. IMO, Skirm sets didn't seem better than green quest rewards after about level 60, so I'd keep my marks for upgrading your weapons. YMMV.
Asking for a guilded crafter to make what's important in teal for you (especially at 70 when the crafted stuff is good) and supplying the mats, is a good option. Doing this could get you purple gear which doesn't require the rarer items... I have 'dressed' several recent levelllers on my server in teal jewellery with left over mats and flakes from my vault. People did it for me when I was soloing and undergeared. Make friends with a guilded tailor/jeweller and you are sorted
The quest rewards in Dunland are good enough for landscape, on level. At 70-75, two or three people can do the great river dailies for the good jewellery barter items and they don't take too long - once you have done the initial quest. (15-20 minutes and even less once you 'have it down'). They are also quite fun. (Some classes can solo these on level.) This jewellery will last you to end game and beyond, if you are prepared to do the grind. Many of us wore this stuff in raids at 85 until we had all the mats for 85 level teal crafted or we got lucky with instance and skraid drops.
BTW: Not all group content takes a long time. As has been suggested, another option is the Moria barter armour, which would see you through to 70's. Turtle Raid is run a lot on my server so that may be an option for some moria meds- it only takes 5 mins, tops, but it is on a daily time lock. My advice is join any of these you can. School or library is also a quick 3 man that you may easily find a third for-especially if you have some higher level friends. Once again, try GLFF. Some people have deeds left over and are happy to help out with lower level content to get them done.Or just to help. Especially if it's a quick 3 man. This applies if you plan on questing in moria for a while or want to try the instances in Galtrev/Dunland and still don't have access to crafters.
At 85, One raid kin has said on forums that they have done BG (to Durchest boss) in about 3 mins. Most reasonable pugs have it done in 10-15 mins. This is the reason it is farmed- it drops pretty sweet loot for little effort. So don't ignore all group content because of your time constraints.
Also if you tell us your server you may be surprised what ends up in your mail! Someone recently asked a similar question and later posted on forums to say that someone crafted them a full set of teal armour! LOTRO crafters often like to help! I have some bits for in my vault for teal jewellery at your level, so if you happen to be on Silverlode, send me a tell.
