Ask people for input IC. Network IC.
There's plenty of 'middle' for a middleman style characters. However, Fixers are based on gaining a reputation, clientbase, connections, etc... starting a Fixer from the ground up is always going to be difficult, there's no instant solution for that kind of thing.
If that's too much investment for you, maybe your IC friends need someone with a particular skillset that you could fill...?
There is -plenty- to do, and don't let an archetype get you bogged down either. Want to be a fixer who also happens to like singing? Great! Archetypes just give typical cyberpunk character ideas
This game is nothing like the cyberpunk I've played before (i.e. Shadowrun, 2020, etc.). At least the way we did it, running jobs (courier/hacks/espionage) work was ubiquitous. Also, fixers existed to pull together crews to do heists and separate the customer from the dirty work.
All I've seen so far here is ghetto drama, a crap ton of gangers, and couriers spamming the SIC with promo. My impression is that a direct service (i.e. a courier, a doctor, a chemist) is much more valuable than being the guy that knows a guy. On top of that, you don't really even need charisma/trading to be a good fixer. My fixer's high charisma stat isn't doing her and favors in a game where all interaction is RP. And trading? Why bother? It doesn't lower shop prices, there's no other NPCs to sell to and make a profit and it doesn't have an impact on negotiations with other players (all RP). I've seen it already. Characters with crap charisma (i.e. "ugly" or similar descriptors) having a ton of juice because they RP'd into it. It's like, you might as well make someone that's functionally capable in something, stats on social skills are a waste of ue.
I had though of doing a chemist (or other crafter) at one point, but after working in the factory, I have a funny feeling that amounts to just sitting at a keyboard typing "chemistry" (or something similar) once in a while so the game doesn't think you've gone totally afk. I've also heard around that decking is a little lackluster in terms of gameplay.
I figure a runner gets to explore, but if the market is saturated, then the lack of work would wear thin. I'm not sure what else would be interesting, though, and am looking for suggestions.
You are still a young padawan in the economics of the Dome, stay the path. Alternatively, if you want to jump to another path, be prepared to slowly grind your way up that path as well.
I promise you, though, if you stick with it and learn over time you will find yourself in a position you imagined, on some level. Biggest key is RPing with folks, starting trouble, etc.
Nobody starts off with respect, and you shouldn't expect yourself to start off from the top because you have high charisma. If you're smart and play your cards correctly, you can rise -very- quickly, but that's rare. However, if you spend enough time, you will -surely- get there.
You should just keep trying, play the game, have fun - RP, build relationships while working towards your goal. That's the point of Sindome.
Also, semi-related, the archtype lists Cha and Int as the related stats, but the skills suggested are Trading, Stealth, and Disguise. Wouldn't Cha and Per make more sense? I'm coupling this with the help file stating that Int is for Technical Knowledge and seemingly more academic things, whereas perception helps with both Stealth and Disguise and a general awareness of one's surroundings seems more valuable than knowing how to fix a car.
