I have a shiny kakuna I would like to know if people would prefer and pay more to buy the kakuna without evolving it or to evolve it into a beedrill which I assume remains shiny and sell it. Reason I am asking because people don't like evolved forms due to slower levelling.

 

Also what is the price of a shiny Kakuna level 10 and a shiny beedrill?

Prices will vary depending on the pkmns stats, and the economy at time of sale.

For best selling price you'll want to lvl it to a lvl 100 Beedrill and ev train it

Shinies also stay shiny when they evolve

Levelling to 100 is too much time and commitment. Is there any way I can get a rough estimate as to the price?

 

Should I just evolve it into a beedrill around level 25, or keep it as shiny kakuna level 25? Which higher price will I get

I'd suggest making a topic in our Rate/Price Checks subforums to get a price estimate (Red, Blue, Yellow). Try to add a screenshot of your Shiny Kakuna when you post as well - it'll be easier for other users to give you a more accurate price check if they can see the Pokemon's IVs and nature.
