Rusting Evap Coils

My A/C (Goodman) started acting up,noticed lines were freezing.
I finally checked the coils and they are rusting .Residue also on the coils(sweet smelling) which I assume if refrigerant. The coils themselves are't really dirty from what I can see.
So honestly I don't know what to do.
1.I can get a mini-split system (which is what I have been wanting)
but even doing it myself is gonna cost 2-3k.
There's the DIY from . Other brands sold on amazon need charging .I would rather have a multi-zone than one big air handler. Makes more sense.But again those need charging and I wouldn't know who to hire.
2.Call a service tech and get a quote on a new coil. Companies around where I am at seem to be expensive. One company quoted me 13k for a mini-split. Yea sure.
Also got a quote on charging if I did the coil myself,30 bucks a pound . Does that seem pricey?
To get the coil replaced they won't quote me on the phone without sending someone out and making 70-85 bucks.
So any advice will be highly appreciated.

Since the lines are freezing there is a good chance it's leaking.
How old is the system (air handler) ?
I would expect a service company to charge a fee for diagnosing a problem and giving an estimate.
Most will apply that towards work being done.

Most A/C companies I deal with will not install any equipment they don't provide.
They will not charge a self installed system.
