Magento < Microsoft Dynamics RMS 2.0 product integration

We require a PHP developer to write a one-way product update script for integration between a Magento database and a Microsoft Dynamics RMS 2.0 database. This does not need to "tie in" with the Magento frontend or backend, so can be a standalone script which is run via cron job. The script must: - Read products from the RMS database (10,000+ products) - One-way product update from RMS to Magento database -- Stock and price updates from RMS to Magento database --- (taking into account non-despatched online orders, and amending the stock accordingly if required) -- Set web products live / not-live, depending on a flag in the RMS database Please advise on ETA and the soonest date this project could be completed by.
