Hello,
I think I've got the skills to take on this project and get it done in a fairly short time. Of course, in order to do that I will need to see the code and all the documentation you've been given by your previous developer. I will also need to see any design documents you may have.
The price I've quoted is negotiable and usually I prefer to work with a per-project costing, but if I'm awarded the project we can iron out the billing. I'm a reasonable guy.
You ask for references, and I hope my references are good enough for you. Please see your private message box for references and information on each reference.
Ready to work. Let's get started.
