Free Traffic Legal Advice

Hi there everyone, hope someone can help me. I live in England.I recently got a letter about a speeding infringement. I was going 80mph on a motorway, in a small van (the limit for vans is 60 mph- which I didn't know) So I got a letter about that. Then I was filmed by a member of the public using my mobile phone to check messages whilst stationary at traffic lights, so two days later I received a letter about that with a notice to prosecute. I currently have 9pts on my license, If I get 3 points for the speeding offence and 6 pts for the use of the phone that will put me on 18 pts. I rely on my license for both my jobs,. I teach apprenticeships and need my vehicle to carry out on site assessments, and I work as a carpenter, so need the van to get to work sites, carrying tools and materials. If I loose my license I would loose both my jobs and probably default on my mortgage, therefore loosing my home as well. I have spoken to a solicitor I found online, she says she thinks she can it sorted before it goes to court, and due to the hardship I will incur if I loose my license, she thinks she can get me off with an increased fine and no ban, or a very small ban. She quoted me £2500 for this. My primary concern is not loosing my license, I don't have a lot of money but I will find it if it means not loosing my license. I want to know if the outcome the solicitor has predicted is correct/likely and if there is anyway of me reducing my costs. Hope you can help.

Thanks,

Leigh,
