Custom CRM and Calculator for Window Tint Business

I need help creating a custom CRM and calculator for my window tint business. I want to make sure that the CRM is nice, short, and simple to use, and that it connects to my Meta ads. I also want my calculator to be connected to the CRM. That way we can input dimensions and film prices to get the result that we're looking for. I'd also like a proposal generator. That way we can send out estimates faster and send out professional proposals as fast as possible, simply by having the info from the calculator go into a process that formalizes a proposal. It can send over estimates as fast as possible and documentation for every client if they need follow-up and things like that. If we can add a follow-up sequence or any other cool features that can help out the business, and just create a system that's very efficient and fulfills all of our needs and wants as simply as possible. Please feel free to reach out if you can help. Pricing is negotiable. Thanks.
