MLS rets data to update wp-property - repost

I have a website I am working on that uses the wp-property plugin for displaying listings. The plugin provider provides a paid addon for a rets connector to download listings. Rets stands for Real Estate Transaction Standard, it downloads data via XML. The rets connector is based on an old version of an open source script called PHrets: [login to view URL] I bought the connector that they offered and eventually figured out how to configure it and make it work to download and update listings. However, my real estate board requires me to delete listings that are no longer on the market and their connector doesn't have the functionality called inkeyindex in order to do this. Their programmers took 4 days to look at a paid support request when the service time is supposed to be 24 hours. I cannot wait any more. The script will add new properties and update them for 4 different property types and do a key index update daily. It will download the raw data and format it so that it appears in wp-property for proper display of information to the viewer. It will run at least once every day. I have detailed information on how I want the script configured, how it should work and plenty of documentation. Previous experience with RETS servers and/or wp-property would be an asset. I am looking for a good programmer for ongoing work also over the course of time, If you are able to do this job quickly and effectively at a good price, I will be working with you again.
