What do you do for a doctor that wants to have a Medlab and do surgeries, install implants, and such? I can’t tell her she can’t do that sort of thing. She has the stats and is willing / already said she would buy or bring the equipment with her from her old life as a cybernetics/biotech medical researcher.
What would I do? Well, first I'd outline to her the constraints on what she can bring with her. Fully-equipped operating theatres are not cheap, and medical equipment beyond immediate trauma care is not generally designed for portability. I would consider the rest of the team and its capabilities and depending on many variables, I'd start thinking about two options:
1) explain that such an aim is a great campaign objective, but will require lots of backing from somewhere, or cash to buy the facilities.
2) considering making this (a) focus of the campaign, bunging a Lab ship (medically focused, obviously) at the party and making it a driving force of your characters' intial aims. Depending on what you *actually* had in mind for the game, this could become pure backdrop, or simply incidental background "intention" as the party become embroiled in something altogether more... convoluted...
She wants to travel around the Spinward Marches and bring medical care to the mildly rich and in need of enhancements and high end Medical services.
Now *that's* speculative trading...!

She really would need a lab ship or an equivalent I think, and a staff. The trouble is, that the "mildly rich" are:
a) rich enough to travel to get their treatment;
b) numerous enough that you land once and don't need to head elsewhere because you're never going to get through them all.
or
not rich enough to pay you enough to cover your running costs.
Potentially, letting your ?idealist? doc find this out the hard way and have to find another way of turning a living out of a hip-deep lab ship debt, is a direction you could drive your campaign.
I think it is a great angle...
It's certainly interesting. You have the option of getting them involved in disaster relief at Imperial behest, and all sorts of other doctoring. Or just using the "peripatetic quack" as cover for any number of different shenanigans.
...would bring a nice income to the team...
This, I think, is entirely at your discretion. Clinics are not cheap to run. Star-travel capable ones especially so. The market could be quite difficult, with long lean periods.
...I need to create some sort of medical system that works with the current material that is consistent and includes costs of medical equipment, drugs, and raw cybernetics/biotech implants.
And the staff you need to provide the care for your patients... also, the market in OTU for implants is pretty small. Military and traumatic amputation/destruction replacements are the traditional limits, though obviously that's your call for your TU. Perhaps a good guideline is base cost of half the RAW price, if that includes installation. p94 gives some prices for extended medical care.
If anyone has a chart or task system like this I would love a copy of it, and if any doctors or medical professionals want to make one I would be very happy!
I'm not sure your game would be improved by going into the minutiae of clinic adminstration. Your big ticket items in the budget are personnel cost and equipments, as well as specialist drugs and augments. You don't want to have a game of "Hospital Administrator"; have someone make Admin and Broker rolls and handwave the details...
