You are a PCI Tier 4 merchant in Visa's eyes. Annual Self-Assesment Questionaires are optional, not required. Compliance validation requirements are set by your acquirer, but should not approach those costs.
Find a different acquirer, or verify that you were quoted fees for a Tier 4 merchant. Should be an hour's worth of paperwork, tops.
