Dear Employer,
My name is Eric, and I'm really interested in your project.
So, correct me if I'm wrong. You're interested in doing a website in which customers can select and pay for a recurring plan (Monthly Subscription in this case), and you would like to use Wordpress as a CMS, and Stripe as the checkout API management, that sounds great!
I would also like to use Woocommerce, so you could have better control of whom your clients are, when will you be receiving payments, etc.
I'm sad to hear you had a bad experience before when looking for an experienced Freelancer to do the website, however, you can rest assured I can deliver the work! In fact, I have done similar things in the past, and worked specifically with Wordpress and Stripe, so shouldn't have any problem there!
I'm asking 250$, the minimum payment. To be sincere, under normal circumstances I would be asking for more for this kind of project, but being kind of new to Freelancer (never been really active before) I have no "website reputation", so I'll have to gain it first ;)
I really care about the jobs I do, I don't want to just take them out of the way, I strive to deliver works I'm proud of, with care and constant dedication behind.
Please, if you have any doubt I'm here to resolve anything that could come into mind, for real, don't hesitate in contacting, no strings attached!
Eric.
