Hello,
Can you share the mock ups of the screen? It will help us to understand the type of app you want and the amount of work is needed. We can prepare a proposal according to your requirements with our final quotation as this is just a cover letter.
We are a company based in India with a team of dot net developers and designers. We have experience in building online stores, job portals, travel portals, saas applications, business websites, portfolio websites, service providing sites, booking engine, taxi dispatching app, mobile sites, mobile responsive websites, etc. So, if you want to see our work we're happy to share. For a quick example, please check our portfolio in freelancer.
We believe a discussion about the project will be convenient for both of us to decide anything so if you are interested please get in touch.
Regards,
OKTeam
