in the next day i will put a website that i was developing for some time online ,
i’m expecting about 10,000 visit/day (kind of e-commerce) so i will need vps ( price must be as low as possible)
but i don’t know how about resources (ram ,cpu, bandwidth), so i will need your suggestions about what resources and hosting company to host my website
Initially all the best for your website. You are thinking of getting 10k visitors on first day and it seems the number is too much for first day. I would still recommend you to consider a Dedicated Server having at 4 GB RAM and quadcore processor.
As for the VPS hosting, I personally recommend InMotion due to my personal experience. Or, why not enter bestvps.us to pick the best according to your needs?
