Being male shouldn't be a hurdle for you but unfortunately, with some, it may be. That is on them though and shouldn't discourage you from doing this, IF it's truly what you want to do and feel you can do well.

If the rate is around $45 though, don't charge $25! This undermines you and makes parents (the good ones IMO anyways) question why you're charging so much less. I think $30-35 would be better. You want this to be profitable, not just extra spending money right?

Before opening, make sure you're doing this for the right reasons and be prepared to explain this to potential clients. Males in this profession aren't as common but it's certainly not unheard of
