Trying to find an affiliate or referral program where I don't require a square space store

Site URL: https://www.theheadshotwizard.com/

I have had several potential customers wanting me to offer an affiliate or referral program if they send people to my website. 

However my site is not a store as I invoice clients after they have used the service.  I need to somehow track these referrals and reward them when customers fill out this form  https://www.theheadshotwizard.com/uploadyourphoto

Is anyone aware of any type of affiliate  or referral program where I can track referrals who submit a form on my website?

Any help here would be great as I have looked at affiliatly and Peaches and they all seem to require a store setup.

It's all about trust in these situations. You could simply clone that form page, set it to no-index in the search engines and then give it to a single affiliate. You can then use a hidden field to add the name of the affiliate to the submission that you receive for tracking. Affiliate then sends traffic to that form.

Your affiliate is going to track traffic inbound so they will know how many clicks it gets.

Because you don't know where in the funnel people are and because you can't let these affiliate leads go to the website because they will not be bother to find the form (unless incentivized), you might need to have an affiliate page that is a landing page - like a mini website in a page. You could create an anchor on the form so the affiliate can link directly to a point in the page. OR the affiliate might do all the pre-sale and explanation on their website.

Bottom line is this, if an affiliate delivers you leads and you don't pay them they will not send you traffic  so again it's back to trust.

Good luck.
