Delphi 2010/Firebird database search function

I have an existing Delphi 2010 / Firebird database project which is a contact management software. It now needs a function to search for records. I would like to find a Delphi programmer who is familiar with Firebird and the DevExpress components, in particular the data-aware ExpressQuantumTreeList VCL component. We need to program a search mask, design the actual search / database query routines, and implement the output of the matching records into a search results page. We also need a very simple function to load and save the search parameters, so that search "templates" can be created and saved/loaded. It's very straightforward, and the budget is 80 USD. I am open to bidders from all countries but particularly keen to hear from Russian speaking programmers because the lead developer is Russian (it may make communications leasier). Thanks, I look forward to hearing from you.
