Hello Client.
Hope you are having a wonderful day.
I went through your requirement and am pleased to say that I got the point to point understanding. As I deal in same matter of concern, this is not at all a big deal for me.
Since a few lines are not enough of a description, I would like you to enlighten me with the queries given below:
Q: Have you prepared any wire-frame for the website and application?
Q: Would you mind telling if the app in android and iOS is friendly only for the latest version or all the past versions or just the last and present, or any other option?
Q: How do you want to sort the search filter? Like do you want a drop down or typing space or may be both in the search box?
Before moving ahead I would like to prescribe certain solutions regarding the matter of concern:
S: I understood that you need help and that you are an expertise in c# and you have just started with asp.net. Let me tell you one thing, "practice makes a man perfect" and as a team we will support each other throughout. Our main goal would be to focus on each other's loop holes and grow together because that is exactly what team means. Also I am well practiced in both languages and know them till depth, and for more you can look at my profile.
Hope I have covered all the things bothering you.
Apologies if your intention was taken wrong.
Looking forward to hear from you soon.
Thanks for going through my proposal.
Have a nice day,
Vijay Singh
