Based on my knowledge, this module is most suitable, may be you need a bit of customization that you may ask developer, but check it out,

https://www.magentocommerce.com/magento-connect/custom-options-pricing-dynamic-products-pricing.html

the steps you mentioned, you can easily create in this products, further more, it supports CSV Matrix pricing as well, a lot more to read on that page...
