Dear sir.
Thanks for offering me a chance to get a job.
I've worked as a software developer at several companies for 10+ years. If you want, I can send you my resume.
I have carefully read your project description and now I understand what you want. I am quite certain about your project.
Don't worry. I will take rid of your problems and worries.
Trust me.
At least, please give me a chance to have a chat with you, then maybe I can offer you a technical support.
I want to tell you that this is not an auto bid.
- Maybe we can come to an agreement for more reasonable price.
- I hope you will remember me and give me another chance to work for you, even though you can't award me this project.
Thanks and regards.
