Hi,
I am expert windows developer having 7.9 years of experience.
I have worked with similar application and I have implemented Estimate, Projects, quotation, invoicing, etc. Also I have worked with Retail POS and in that I have implemented same functionality.
Please can share detail requirement document or task need to consider for this scope so I can share exact time frame and cost.
I can deliver work on time with very good quality. I am sure, once you will work with me, you will hire me for your future work because of my quality work.
Looking forward to working with you.
Thanks.
Regards,
