Hi,
Approach:
I have prepared similar tools in my official work. We call it 'build your own' products. Customer gets a fixed amount/point and chose among various features untill their points get exhausted.
Final product configuration (no. of products chosen) can then be automatically mailed (through excel itself) to entered email-id (using gmail server).
I can provide you a program in Excel to do it. You will need to put it in website.
My background:
I am working as Lead Pricing Analyst in a Fortune 500 MNC. I have worked on pricing models, income statements, value-pricing projects etc. I have worked extensively on business analysis, excel and VBA in my job and here on freelancer as well.
I believe I can help in your work. Please have a look at reviews provided by previous employers.
Please contact for further discussion.
Regards!
Vikas
