Excel - refining the worksheet, arranging formulas, data

Hello, I am looking for a person to develop an invoice for me in excel so as to block individual cell changes. The invoice is ready in excel, only the relevant cells need to be blocked in such a way that the data cannot be changed.

I urgently need someone proficient in Excel who can generate the names of goods based on rules, e.g. XX-YYY-ZZZ, where X = 1 v 2 v 3, Y = A v B v C, Z = 0 v R, i.e. I provide the logic for creating the names, and I need them generated.

I am looking for a person who will make me formulas from Excel data (VBA or other simple possibilities come into play). The Excel data is already prepared. In the future I will want to supplement the file with new data. In short, from the data that is already in Excel I want to flirt data according to my needs. E.g. averages/totals number of goals/cards/penalties of a team in a season, a year or in the last 5,10 games, etc., further after selecting "team" from the list I will see the statistics of a particular team. Then comparing 2 teams I add for example Arsenal vs Liverpool and it shows stats: team vs opponent from last matches, season etc. (I can choose from how many recent matches it should show). In general, I am open to suggestions, ideas and help to make this clear and functional. I will try to give more details, information or questions on priv. I am looking for a person for whom doing such things will not be a problem and maybe will offer his vision of how it can be done practically etc., because I unfortunately do not know the functionalists of Excel so as to use it 100%. Interested persons please contact me. Remuneration to be determined. In general I am open to suggestions, ideas and help to make it clear and functional.
