Looking to buy SaaS business - Budget of $5k

Looking for a profitable business or one with clear growth potential. Must have low operational overhead, preferably automated or minimal hands-on work. Requires a clean codebase, good documentation, and no major technical debt. Niche market preferred, especially B2B or tools with loyal user bases. Needs transferable assets including website, domain, code, customer list, and related accounts. Not interested in idea-stage projects, pre-revenue prototypes, anything requiring a large team, or anything dependent on a single non-transferable custom integration.
