I need an SEO expert to work on "revenue sharing on business generation” model

After the India govt. made every business in India compulsory to be GST compliant, there is a great demand for a good GST compliant Invoicing, Accounting & Inventory software in the market this time. I have got a beautifully designed & developed software and website ready with me- gstinvoicer.in. I invested a lot of my resource- both time & money and now like some expert to promote it online. I also like him to SEO the website to improve Google ranking and route meaningful traffic to the site that has potential to convert into actual business. If promoted & marketed properly, the software has a potential to generate huge business. Through “revenue sharing on business generation” model, the SEO partner can earn Rs. 1 Lac/Month onwards. I see a possibility to collaborate with someone if: (1) He is proficient in both on-page & off-page SEO through various white hat techniques with objective to promote the website to Google India page rank 1. (2) If he is expert in various other online promotion techniques which result in increased meaningful & relevant traffic to the site which has potential to get converted into actual business. I like to promote the site holistically, instead of just focusing on SEO. (3) If he is ready to collaborate with me in this venture, do his part (SEO & Promotion) and share profit as the business grows. We can formulated a profit sharing model for each converted business.
