Should I hire freelances to write for my website or should I do it alone?
I have a side project that I'm working on after my regular 9-hour job. It feels like it's killing me already because I spend a lot of energy working on both projects (company's and my own). Any advice?
You should do both! Your website is your voice. In an age where people buy from people, you should market yourself as much as possible through your own voice.
At the same time, you want to get your message across to as many people as possible, and that starts with having more content. You can hire writers, and you can even offer the ability to guest post on your website so that others who share similar messages can promote both themselves and your brand.
I've been in business development for some time now and have been writing even longer but my message wasn't reaching people until I started guest posting and contributing. In turn, my message has the ability to reach more people, therefore, I have no problem with writing more content for other websites.
I hope that answers your question. You can and should be doing both ideally.
Both things will be good for you. If you have sufficient funds then you need to hire a content writer to save time and focus on website activity dear.
Better do both to get more mileage, however, you know the vision better for your website so translating that when working with others is of the greatest importance.
