My question involves labor and employment law for the state of: Texas

I recently applied for and successfully got hired for a remote position as a cryptocurrency trader at a private cryptocurrency trust, a position that I found on a job search website. They got back to me saying I was their most qualified candidate and they sent me an employment agreement to sign and told me to register at their website. I registered then printed and signed the employment agreement. I faxed it back to them, and now I havent heard anything from them for about a week. They wont return my calls or email me back about my training or anything? What legal options do I have now that the agreement is signed? Should I look for a job while Im still technically under the terms of the agreement? Is a lawyer a good idea at this point?
