Hello Sir,
Placing a one liner in the project description is as good as saying, "I want a car, please sell me one"! You need to be more specific than that. We have done several ecommerce projects but if you are genuinely interested in getting this project done please send me the following details.
1. Link to your existing website.
2. Please specify the modules to be integrated.
3. Please specify the API sources.
4. Please specify the core functions you are referring to which needs to be updated.
5. Please specify the payment gateway to be used for the subscription.
6. If you use any payment processor which required payment details to be entered on your website itself, then you would need to purchase an SSL certificate (preferably from your hosting provider)
Look forward to here from you,
Thanks,
Prasun
