After reviewing the requirements, I believe my company would be a good choice for this project.
I have been in the IT business for 15 years and began programming in 1983. I have worked on large enterprise systems at Bank of America, Wells Fargo Bank, Walgreens Pharmacy, Delhaize, and GM to name the big ones.
My company is an American owned software development company based in Thailand and we have a team of Senior American and Thai engineers. We are able to offer superior design as a result of working with so many diverse enterprises.
My company is able to offer rates as good or better than any LEGITIMATE off-shore company in PHP, Java, .Net, Web 2.0 technologies. We will not be the cheapest, but our guarantee, quality of product, and post-delivery service makes us the best value.
If you can provide complete specs, I can provide references, sample work, and a quote. I guarantee my work.
