You sound like me Erin! I don't want a matching band either.
It is 9ct, 18ct gold/white gold?
What is the thickness and high profile of the ring?
How many diamonds, carat weight, colour, clarity??
I got quoted $700 for a 1.8mm (H) x 2.0mm (W) knife edge, plain platinum band through a reputable retailer. I will probably end up going with the Tiffany band FH said I could have since it's only an extra $140.
I am not sure if you've just visited a shopping centre jewelry store or gone to an actual jeweler but don't forget that all jewelry retailers have huge markups. Even though you're paying $2k for it, you need to think is it actually worth what you're paying? If you take it to a valuer for insurance purposes they may say it is worth less than what you've paid.
If I had 2k to spend on my wedding band I would definitely get it made.
