Basic quotation software

We are a Bathroom/Kitchen/Laundry renovation company and ESSENTIALLY we are looking to build a quotation platform that will allow us to sit down with a client and generate a quote on the spot. This would require a two phase questionnaire - STRUCTURAL (with inbuilt metrics - we have all this information organised and at the ready). AESTHETICS (essentially imported catalogues from our preferred suppliers so they can select bath tub A,B,C for example. This would be quite extensive and would require an option to insert a bespoke choice (like a notes section). Once this information was gathered the software would need to generate a quotation summary, outlining scope of works and total cost. Ideally we would like to build on this in the future and potentially work in a client/admin CMS but this is not something that we are looking to address right now. We just need to build a platform that can make quoting a new job simple easy and transparent. We have templates and an example of something similar, along with all required data and catalogues ready to go. We just need someone to design something so we can utilise it more efficiently. There would be ongoing work for the right person to update pricing and catalogue content. Along with building out the platform in the future. Happy to discuss pricing once details are discussed.
