For now definitely plug your car in using the 110V adapter. It will give you a 3 mph charge rate and keep you driving until your final solution is installed.
If the electrician is coming out to give you a quote and you haven't mentioned your car yet, just ask for exactly what you need to get the quote. Park the car down the street while the electrician is there. Not kidding. Quotes for these installs are proven to go up dramatically if it is for a Tesla vs. RV, for example.
If you are uncertain about how long you'll be in the house you can save a little money by putting in a NEMA 14-50 outlet. Most electric vehicles can use the outlet so you can easily leave it there when you move.
If you are not planning to move any time soon the High Power Wall Connector (HPWC) with the 24 foot cord is probably the best option. This allows you to keep the charging cable that came with your car in the vehicle in case you find that you need to charge while away from home and can't make it to a Super Charger (SuC) or a destination charger for whatever reason. The longer cord will allow you to charge outside the garage or in another garage stall if needed.
