There are 4 main possibilities:
1) Use a nearby ordinary single phase household socket. In Switzerland that has mostly around 230V and a max. of 10A. If you have one, cost 0.
With this you can charge overnight - say over 12h about 30 kWh. With those you can e.g. drive daily to work and back with a 130-160 Km round trip. At home I charge mostly in this way.
1a) Use a nearby 16A plug (such as Type a 23 in Switzerland or a blue CEE, often used to connect washing machines), cost as above and your daily roundtrips would be stretched by a factor of 1.6 (200-250 Km)
2) Upgrade a line to 16A, mount a blue CEE single phase socket (so called camping plug socket or a Type 23). Cost of pulling lines is location dependent. Same driving range as above.
3) Install a three phase line and mount a 3x16A red CEE socket. That provides 11kW. You probably have such a plug and cable for your S. That will charge your battery overnight from nearly empty to full, if you have a 100 kWh Model S. Cost entirely location dependent.
4) Install a three phase line and mount a 3x32A red CEE (22kW) socket and/or a Type 2 Tesla Wallbox. Then in 6h or so you could charge some Model S that have a 22kW charger fully. Costs without counting the Tesla Wallbox is entirely location dependent. Expect about SFR 2000.- without a line to be pulled to the main panel and eventual changes to the panel itself. Heavy items in this are a special FI at 750.- and an interruptor on the main panel required by EWZ as soon as you say that you will use it to charge a car, which is evidently the case with the Tesla Wallbox. Mostly this has to be downgraded to 3x16A (11kW) as the main panel may not permit more without major work and it may not be necessary as most cars cannot take more than 11kW AC anyway.
It is evident that a quote will need that:
a) you specify what you are looking for in terms of 1) to 4) above,
b) an electrician has seen the place.
As you are not planning to use that installation for long, I would think that solutions 1) or 2) might well be all you need at home.
