Hi There, Hope you are doing well,
Interested in your posting as I’m used to performing such projects (See Profile). I’m ready to have a look and start right away if you give me a chance. Please share more details/file/sample in order to assess the work expected and run a draft. It's not confusing, however needs clarification. JUst confirm the all data for vendors are arranged with the same format and items are unique and having same name in all vendors data. If it's theecase, it's very easy to design a search table where you enter material and get all vendors with prices arranged with highlight of lowest. Don't worry it more simple than you imagine.
I would like to assist you at a reasonable price along with high-quality work delivered on time.
Looking to hearing from you soon,
Thanks & Regards,
Leo,
