Magento - Need simple Function to Change Product Type

I need a PHP developer intimately familiar with Magento and Magento my SQL database. I need a simple function created, no user interfaces needed since it can simply be added as a pulldown option on the Manage Products screen. I have already implemented code I found on the web to change attribute type in the same way. here are some examples of how to change attribute type and I imagine product type must be very similar: [login to view URL] [login to view URL] and this is a free extension with open source code that can also be studied on how to quickly turn Changing Product Type into an extension you could sell since almost everyone with Magento as a need to do this as they are working on organizing their products or after importing... http://www.magentocommerce.com/magento-connect/Flagbit+GmbH+%26+Co.+KG/extension/706/change-attribute-set I have also read that it is possible to change the product type by simply changing a value of 1 table entry. "Table is catalog_product_entity and its easy to change the type". I thought I read this somewhere two months ago also, possibly the same forum post. It is the very last forum post on this page: http://www.magentocommerce.com/boards/&/viewthread/211045/#t279628 It references that they found the code somewhere else or that it already exists, but the link is no longer valid. I cannot believe no one has turned this into an extension. My only worry is that it is not as easy as these comments imply. But if you are intimately familiar with Magento you should already know the answer to this? I am looking for bids on providing me this function or bit of code that I can add to [login to view URL] to obtain the extra pulldown menu entry. (I know I do not have a historical profile here on freelancer, but I have worked with a number of outsourcing projects with professionals on oDesk. I pay promptly and success with this project could lead to others)
