What I usually use is Upwork, just google it. I am not in any way affiliated with them, but you get any type of work done very fast and it works for me.

I always go with the fixed price option (not the hourly rate), it saves some money. Look for people from Nepal, they are usually cheap, fluent in English and finish the job.

Cheers,

Congratulations on the new company. You can outsource work by using an independent contractor agreement. However, you should be careful to ensure that the agreement protects the ownership of your intellectual property and protects the confidential information of your client. Please feel free to reach out if you'd like to discuss how to accomplish this.
