Development of keyword research software

I am looking for an experienced software development company to build a web-based keyword tool to be hosted on one of my websites. The software will be web-based, and built in PHP, with a MySQL database. The software will be hosted within a members-only website. The host website is built on Wordpress. The software will need to be built to work on the major browsers (FireFox, IE, Chrome). I will need an Admin panel for the software, in which I will be able to view usage statistics for the software. The software will be able to perform the following functions: ## Deliverables **Request for Proposal** **Development of Web-based Keyword Tool** **Purpose of this Request:** The purpose of this request is to solicit proposals for the development of a web-based keyword tool. **Background on Software:** ** ** ? The software will be web-based, and built in PHP, with a MySQL database. ? The software will be hosted within a members-only website. The website is built on Wordpress. ? The software will need to be built to work on the major browsers (FireFox, IE, Chrome) ? I will need an Admin panel for the software, in which I will be able to view usage statistics for the software. ? The software will be able to perform the following functions: Keyword Research: 1. Users will be able to enter a "seed" keyword or URL, and the tool will go to the Google Keyword Tool, enter the seed keyword or URL, and download the results. Keyword Sorting: 2. Users will be able to paste a list of keywords into the tool, and sort that list by frequency. There already exists a tool online that does this. The tool is at [login to view URL] I would like my tool to perform the exact functions as the tool on that page. 3. Users will be able to paste a list of keywords into the tool, and return only keywords containing a specific word. There already exists a tool online that does this. The tool is at [login to view URL] I would like my tool to perform the exact functions as the tool on that page. Keyword List Cleaning: 4. Users will be able to paste a list of keywords into the tool, and "clean" that keyword list, by performing the following functions: a. Remove duplicates from the keyword list b. Remove particular characters from the keyword list (i.e. characters that the user specifies. For example, a user might want to remove characters such as * from all keywords) c. Capitalize the first letter of all keywords d. Add prefixes and suffixes. (In this case, the user will be able to paste a list of keywords into one text box, and a prefix and suffix into two other text boxes, then click "Combine keywords", and a combined list will appear.) Keyword Grouping: 5. Users will be able to paste a list of keywords into the tool, and the tool will automatically group a list of keywords based on root word. There already exists a tool online that does this: [login to view URL] Keyword Preparation for Export to Adwords: 6. Users will be able to paste a list of keywords into the tool, and the tool will generate phrase-match and exact-match keywords from a list of keywords (i.e. the tool will generate two lists: one with " " around the keywords, and another with [ ] around the keywords). I have attached a diagram of what I would like the interface for this tool to look like. **Ownership of Deliverables:** Complete ownership of the keyword tool will remain with me. **Payment Terms:** Payment will be provided to the vendor? I will expect the vendor to fix any bugs (at no cost to me) within 30 days after the project is completed. **Required Bidder Information:** Bidders should provide the following background information on their company: - Types of software projects your company has completed - Whether or not your company has built web-based keyword tools. If your company has built web-based keyword tools, please provide a description of these tools, and links to any tools that are online. NOTE: I can provide a mock-up of what I how I would like the tool to look.
