For example, if you pay yourself $50 / hour and it takes you two weeks to design a website but you also have projects X, Y, Z that will suffer because of you trying to figure out the website, what will this cost you?
If we assume $50 per hour x 8 hours in a day x 5 days in a week x 2 weeks = $4,000 . Once the site is up then you may realize that you did not brand properly or there is an error in the code you cannot figure out and you have no idea how to even keep the site secure so that is even more time wasted. Then on top of it, you also have to think about whatever you are losing by not working on X, Y, Z plus the stress that will cause your health to suffer. What if you could hire me and not have to worry about having to redo errors or from getting blacklisted because you got hacked and instead, just focus on X, Y, Z which is not only your passion but the money makers?
Or what if you could go home an hour earlier everyday to spend with your kids because someone is sorting/automating your emails? That way when you start in the morning you can just hit the ground running or maybe even wake up to a bunch of new leads because you are "replying" to customers 24/7.
There are so many more worst case scenario's I can help prevent but it all comes down to one thing - What is peace of mind worth to you?
