Basement Mother-in-Law Conversion

Hello,

We would like to convert a portion of our basement to a mother-in-law type option.

We'd like to convert a large storage room, basement bedroom with it's own entrance and an existing bathroom to belong to the suite. I've attached a rough plan.

We'd love to DIY a fair bit of the finishing but the heavy lifting/trades are best left to professionals obviously. I'm curious what the ball park for something like this would run. I've seen anything from $25-50/ sqft

Notes:

- Bathroom is existing 2 piece (63"x93"). Would need to add plumbing for a tub/shower

- Ok with simple tub/shower kit

- Framing can stay in bathroom with modification to door opening location

- Would require minor electrical changes

- 90% of main area is framed and insulated, very little is dry walled

- there's existing plumbing where wet bar would go

- electrical work to move lighting etc in main area

- would like to add a window (for light, not egress). raised bungalow so plenty of room to cut above the concrete.

- planning only a wet bar with fridge, no cooking appliances, to avoid legal suite rules (this isn't for long term renters)

- top and right walls are exterior. others are interior to other areas of basement
