Is $3,200 to add batts over existing basement insulation blanket a fair price?

I'm based in Canada Toronto, planning to insulate and frame my ~900 sqft unfinished basement, focusing only on the exterior walls (about 120 linear feet) with no partitions or drywall yet. The top half has the original builder-installed insulation blanket, but I want to redo everything properly to qualify for Ontario’s energy rebate ($900 for R14 above, $1500 for R23+). After some research, I thought the best approach would be XPS rigid foam + batt (e.g. R14) with 2x4 framing, which should meet the R-value. But every contractor I talked to seemed to avoid using XPS foam and gave wildly different quotes. As a homeowner with limited experience, I’m really not sure what makes sense anymore.
