"There's no such thing as Free"

Joomla is free. Free to download and free to use. But wasn't there an English proverb that said: "There is no such thing as a free lunch" ?

Construction of a website

The best way to install Joomla requires certain technical skills, knowledge and time. To gain such technical knowledge and skills, you need to invest time and money. The time you need, you can not spend on your own business. And that costs money.

A solution could be to outsource the installation, for example to db8 that has the necessary technical skills and expertise. But outsourcing is not free.

Operational website

You have your own Joomla website. The installation has been done and your website is well visited. To attract visitors it is essential to keep your website up to date.

You can outsource the management of your website to third parties. That costs money. Or you can do the management yourself. But that costs time. But not much more time than writing articles and email them to an advertising agency who puts it on the website. So it costs a little time.

Joomla is very user friendly. However to get the best out of it, a short Joomla course is recommended. Also not free.

Website support

After a short course, you can manage your own website. But what do you do if you have further questions? Help on the official Joomla forum is free, but you probably already guessed it, indirectly it will cost time and money. But for support from third parties, you also need to calculate some money.

Joomla is, in itself, free.

It is up to you to determine what you want and can do, and what you're willing to invest in building knowledge, time and money. Find an optimal mix. Which depends on your knowledge and drives.

Putting articles online is something that you could easily do yourself. For a single installation, configuration and partially adding articles to a Joomla website, it up to you to decide if it's worth a (time) investment. A short training is recommended for optimal use of Joomla. For questions you can first do a brief search on Joomla forum, followed by a paid support from a Joomla professional.

Conclusion

Do not want to do everything yourself, because it can save you money. Time not spend on your own business, can not be used to generate turnover.

It's your choice what you can and want to do, and what work you want to outsource e.g. to db8.
