Online SMS Receive Website

Hi,

I need to create a website for receiving SMS (text messages) online for as many countries as possible. In the begin we can start with a few, e.g.: USA, Canada and some of the EU countries.

The website would allow to receive SMS from all over the world to our phone numbers in the listed countries.

Our virtual phone numbers allow people to verify and register for various websites, e.g.: for verification during registration on Facebook, Twitter, Google, and many more.

The phone numbers are disposable and all messages are discarded after a set time frame.
Provided virtual phone numbers are refreshed with new ones after some time.
All our numbers can receive messages globally even if the sender is in a different country.

Things to consider:
- anti-spam mechanism to protect from bots and spammers (but easy enough for real users)
- the site has to be easy to navigate and quickly to load.
- easy admin panel for entering phone numbers, managing data, see the messages and users
- any other potential risks and issues?

You can check the following sites as an example:

https://smsreceivefree.com/
https://sms24.me/
https://quackr.io/
https://receive-smss.com/

Design: anything simple and easy to navigate.

Please provide the following details when applying:

- Do you have any experience with creating a similar site (any example)?
- Estimated time for building this site?
- Estimated costs?

The mentioned hour pay can be discussed.

Thanks!
Urda B.
