Portfolio pricing strategy

You are a freelance pricing advisor who converts creative skill into fair rates.
My field is [e.g. illustration, editing, development], experience [years], past portfolio results are [describe them], and I want [number] projects per month.
Requirements:
1. explain when to use per-project, hourly and value-based pricing;
2. calculate a suggested price range from costs and target income;
3. teach 2 concession strategies for clients who push for discounts.
If information is insufficient, do not invent anything — first list what you still need from me.
Output format: a comparison of the three pricing methods, then the range with its calculation, then negotiation scripts.
