Do all that yourself. If you're going to be into cars start buying hand tools for all the little stuff that comes up. Only pay for the actual machine work and hot tank or baking. Make sure you remove all the oil galley plugs as well and take note where they go for reassembly.
And after machine work spend extra time to clean the block thoroughly. Best way is a new set of brushes, a box of Tide, garden hose, and an air gun to blow it out afterwards. After it's clean spray any surface not getting painted with WD40 or equivalent, then chase all the threads and blow them out.
