Wordpress hositng from a decent provider ...

What do you think of using Wordpress hosting from oissite.com? Are they the best in this realm?

I would suggest you to check out some of the best wordpress hosting provider through Google search as well as from review session of this forum so that you can get better option for query.

WordPress works best on a Linux Server which is also the most popular operating system for web servers.

I would recommend you to go with Microhost company. Their services are extremely reliable and amazing. I am personally using their service support in chepaer rates. They are always available in 24*7 technical support to help their customers in solving their problems.

You can rely on hostwinds.com web host. Excellent service, very friendly and knowledgeable.
Nice selection of included scripts, CPanel, MySQL control panel, and many others that the high priced sites do not offer or support.

yes they are the best, I suggest you try their services.

Have a look at Wordpress-friendly services from A2hosting.com (ZIP51) and QHoster.com (happy2018), plans contain many useful resources which help to run websites smoothly and reliably.

I don't find the website promising. I think you should not trust someone who doesn't look promising

Even I don't find website convincing. I think you can select 1and1, hostgator, hostinger and fastcomet are great available options.
