Hello Mr/Ms,
I'm interested in working for you. I have already worked in a CSGO betting website in the past and I believe I'm able to fully develop the website according to your preferences. I like to satisfy every client I have, and communication for me is the key to achieve this.
I've been working with node.js, javascript and web development for more than three years. If you have a web design in mind, I will do everything that's possible to create it :-)
In regards to this kind of website, there are a few things that we should discuss. One of them is the method to get prices from the Steam market. Since the Steam market's API limits the number of calls to 20 per minute, it's not efficient to use it for the website. However, there are many others 3rd party websites which supply the prices, some of them for free. This isn't a problem, just a matter of preference.
If you're interested in working with me, please let me now. I'm looking forward into working for you!
PS: I already have the bots' system done. Because of that, the development of the website may not be longer than 20 days. Also, I will provide free support in case of Steam updates.
