How to arrange a work shadowing visit in Finnish

I'm really excited about a Finnish course that I'm teaching for nurses right now.  Since I'm not a nurse, I'd like to visit a nursing home or a hospital and observe the language in real situations. This is what I said when I called to a local nursing home earlier today:

• Tässä on ______. - This is ________ speaking. 
• Toivottavasti mä en häiritse, mutta.. - I hope I'm not disturbing you, but..
• Olisiko mahdollista tulla tutustumaan teidän palvelutaloon?  - Would it be possible to come to observe your nursing home?
• Mä haluaisin jutella hoitajien ja potilaiden kanssa. - I'd like to talk to the nurses and the patients.
• Mä ymmärrän, jos se ei ole mahdollista. - I understand, if it's not possible.
• Mä voisin tulla milloin vain teille sopii. - I could come whenever is good for you.
• Se sopii hyvin. - That suits me well. 
• Kiitos tosi paljon. - Thank you so much.
• Nähdään silloin. - See you then.
