Dear Sir/Mam,
I have read you project description and understand perfectly what need's to be done.
I have been in this industry for 4+ years and such jobs are my daily practice.
I can assure you that if you work with me once, you will always work with me for these kind of projects.
I have bid a comparatively lower amount.
Please feel free to ask questions before awarding the project.
Thanks & regards, Ganpat Desai
