developer needed for simple logic range

Hi guys, I'm looking for someone who knows typeform to help me improve the one we have for our business: https://supremegreen.typeform.com/to/VjVH9o
We want respondents to be able to choose their own selections of products we offer and get a range in price.
We also wanted help in trying to build a new Videoask of the same sort of questions.
I'm happy to pay someone for the service in setting it all up. Just not sure who to ask.

Thanks for your help.

Cheers

Paul
