Wooden Frame Matte Preservation

I have a solid wooden frame that is structurally sound but has lost its luster over time. I only need it polished and finished—no structural restoration or pest treatment—so the wood looks refreshed without changing its character. The final appearance must be a smooth, even matte finish, free of streaks or glossy patches.

Please outline the steps you will take for surface preparation, the type of polish or sealer you plan to use to achieve a durable matte sheen, and how long the cured finish will need before handling. Photos of similar matte-finished pieces you have completed will help me choose the right freelancer.
