I'm in UK got some vials late last year and I can't be 100% sure (would need to look at my bank statements when I'm back home) but I think it was this company.http://www.soapmakers-store.com/
Click on BOTTLES AND PACKAGING link then INSERTS AND CAPS.
The glass vials I have are slightly different to the ones you get most perfume samples in - mine have black screw-on caps. Not sure about suitable funnels though - you could phone/email them and ask if they sell them. If its just a single funnel you're after then I may have one at home that you can have - it depends on what size the stem has to be.
