Online company looking for a modern and simple Twitter header

We are a SaaS company that helps people earn an extra income every month. We do this using a mathematical algorithm that allows us to always win against online bookmakers, without any risk of losing money. This industry is called matched betting and is most known in UK, in case you want to google it. Our main challenge to attract new customers is trust, because regular people who don't bet online, distrust everything related with gambling, and that is what we want to avoid. We are not gamblers, we help people earn money without risk, so we want the twitter header to convey trust and confidence, while avoiding aggressive symbols like cash, casino chips and stuff like that. We want the Twitter header to be modern and simple. Additionally, as we already have a logo and a website, we want a design that matched their style. You can see them here: https://againsttheodds.es Our target demographics are 30-50 y/o people who want a side hustle with which they can earn some extra money. Males are more prone to try our service than females, and people who have already a high income are not our targeting.

The name and logo of our company should be used within the design.

We absolutely want to avoid references to Casino and gambling, like cards, money, chips etc. We use betting to make money, but we want to be seen as an investment option, rather than anything gambling related.

Every design category has flexible pricing for all budgets. Social media page starts at $79.
