My recs in no paticular order
Neut Fixer for ease of travel, GSF, & HnQ.
GMI is hardly dead but it is paid only to sell on. Made around 30m+ last couple days with necro cloaks & Complete Mariner’s Father books & shop food.
Following the quest list will get you to level 15-20 in an hour:
Arete quest list (I may be a bit biased 
)
Do it to at least level 5 and grab Janos’s quest.
Do the stolen handbag when you leave Arete-- instant ding. Then go to the holodeck & see Ralph & go get mutant flesh from the rewards terminal next to him. Then grab the freelancer missions from the drone in the same room in the back. (the drone is up only every other week-- up now, gone this Sunday.)
Then go sign up with mission agency, grab the daily elite, regular daily, and AI daily.
After doing those I’ll go to SL & do both redeemed & un-redeemed first garden key quests. Takes about 2-3 hours to level 60 or so.
